Applications and Design‑In Guidance
- 12‑V automotive body electronics: Drive lamps, small solenoids, small heaters, and similar loads within the 0.75 A/channel limit.
- Distributed power switching: Replace relays with solid‑state, protected high‑side control to improve reliability and reduce acoustic noise.
- Module consolidation: Use both channels to control separate loads, minimizing BOM and PCB footprint compared to discrete MOSFET plus protection circuits.
Design tips:
- Current limit: Each channel supports 0.75 A. Ensure worst‑case load current, startup inrush, and ambient‑to‑junction thermal rise remain within limits.
- Voltage range: 3.4–40 V operation suits 12‑V automotive rails and tolerates typical system variation. For operation in other environments, verify compliance with the applicable transient/EMC standards.
- Thermal: Use the PowerPAD with sufficient copper area and vias. Evaluate temperature rise during continuous load, especially in elevated ambient conditions.
- Inductive loads: For inductive actuators or solenoids, include appropriate external snubbers or diodes if required by your system constraints and per TI guidance.
Why Choose TPS2H000AQPWPRQ1 for Automotive Designs
- Automotive‑qualified (AEC‑Q100) device aligns with OEM quality flows and PPAP expectations.
