VN5770AKPTR-E

STMicroelectronics VN5770AKPTR-E VIPower Quad High‑Side Driver for H‑Bridge Configurations

STMicroelectronics VN5770AKPTR-E is a quad smart power high‑side driver built on the VIPower platform, designed to simplify complete H‑bridge configurations and general‑purpose load switching. Packaged in a compact PowerSSO‑24 for surface‑mount assembly and supplied in Tape & Reel, it targets robust control of resistive and inductive loads while integrating protection and diagnostic capabilities typical of VIPower devices. If you need to consolidate external MOSFETs, sense resistors, and discrete protection into a single automotive‑oriented device, the VN5770AKPTR‑E offers a clean, high‑density path forward.

Why engineers choose the VN5770AKPTR‑E

• Quad channel architecture enables multi‑load control or pairing of channels to build H‑bridge topologies for bidirectional actuation.

Architecture and design intent

The STMicroelectronics VN5770AKPTR‑E integrates four high‑side smart switches into a single IC, enabling designers to manage multiple loads or create a compact H‑bridge by pairing channels. In H‑bridge arrangements, two channels are assigned to each motor terminal (one per “high side” leg), and direction is selected by driving the appropriate diagonal pair. This method suits DC motors, bidirectional solenoids, latching actuators, and similar loads that benefit from controlled reversal.

By concentrating the switching, protection, and diagnostics into one device, the VN5770AKPTR‑E can reduce PCB area and simplify wiring harnesses versus discrete MOSFET and driver circuits. This is particularly advantageous in automotive and industrial control nodes where reliability and maintainability are essential.

Using the VN5770AKPTR‑E in H‑bridge designs

When arranged as an H‑bridge, the VN5770AKPTR‑E’s four high‑side channels can be grouped to provide controlled bidirectional current through a load:

• Channel pairing: Assign two channels to one motor terminal and the remaining two to the other terminal. Direction is chosen by switching the appropriate diagonal pair, while the opposite pair remains off.
• Current flow management: Because all channels are high‑side, energy recirculation and demagnetization for inductive loads must follow the device’s recommended operating modes. Carefully review the datasheet’s application notes and clamping behavior to ensure compliance with allowed inductive energy and voltage limits.
• PWM and speed/force control: If PWM is supported within the device’s limits (Not specified in datasheet), modulating the on‑time of the active pair allows speed or force control for motors and solenoids. Confirm maximum PWM frequency, rise/fall times, timing constraints, and thermal considerations in the datasheet.
• Diagnostics and protections: VIPower devices typically integrate sense and fault reporting. Use these outputs to implement real‑time fault handling, load diagnostics, and system health monitoring. Verify the signaling levels and reporting modes in the datasheet for proper MCU interfacing.

Design recommendations:

• Thermal design: Allocate adequate copper area and thermal paths under and around the PowerSSO‑24 package. Observe layout, spacing, and thermal‑via recommendations in the package application notes.
• EMC/EMI: Route high‑di/dt paths tightly and provide robust supply decoupling near the device’s VBAT and logic pins. Add input filtering where recommended by ST reference designs.
• Inductive load handling: Respect clamp energy ratings and ensure that transient suppression at the harness level is compatible with the driver’s internal protection strategy.

Typical applications

• H‑bridge configurations for DC motors and bidirectional solenoids
• Multi‑load channel control in centralized body control or industrial nodes
• General‑purpose load switching for resistive and inductive loads
• Consolidation of discrete high‑side MOSFETs and protection networks into a single smart power IC

Packaging and assembly

• Package: PowerSSO‑24, 24 leads, surface‑mount
• Packaging format: Tape & Reel (TR) for automated pick‑and‑place

Assembly notes:

• Follow ST’s recommended footprint and soldering profiles in the datasheet to achieve proper wetting and coplanarity.
• Consider thermal relief and copper pour strategies to manage junction temperatures under expected load profiles.
• If conformal coating or sealing is used in harsh environments, verify compatibility with the package materials and cleaning solvents.

Compliance and environmental

• RoHS/REACH: Not specified in datasheet
• Automotive qualification: Not specified in datasheet

Actions for compliance teams:

• Obtain latest environmental and material declarations from ST’s product page (see links below).
• Confirm regulatory status and regional compliance (e.g., EU RoHS, REACH SVHC) prior to release.
• Validate part number suffixes for any eco‑pack or plating variations if required by internal standards.

Lifecycle and sourcing

• Lifecycle status: Not specified (verify on STMicroelectronics product page)

• Approved alternates: None listed in this record

Sourcing tips:

• Use the exact MPN “VN5770AKPTR‑E” when querying distributors to ensure you get the PowerSSO‑24, Tape & Reel variant specified here.
• If your build requires alternate packaging (e.g., tubes vs. reel) or different suffixes, confirm the ordering code tables in the official datasheet/product page.
• For long‑term programs, request a formal Product Change Notification (PCN) subscription from ST or your authorized distributor and review ST’s longevity commitments where applicable.

System integration considerations

• MCU interface: The driver’s control/diagnostic pins should be tied to robust logic references with proper ESD and transient protection according to the datasheet. Confirm logic‑level thresholds and any need for pull‑ups or pull‑downs (Not specified in datasheet).
• Power integrity: Place bulk and high‑frequency decoupling near the device. Harness transients in automotive environments can be severe; front‑end protection should align with the driver’s absolute maximum ratings.
• Fault strategy: Implement software handling for overload, thermal events, or open‑load conditions if supported. Logging and graceful degradation improve field reliability.
• Derating: Observe current, temperature, and duty‑cycle derating from ST guidance to maintain junction temperatures within limits (Not specified in datasheet).
