A good PCB layout for the DRV103H involves keeping the high-current paths short and wide, using a solid ground plane, and placing the input and output capacitors close to the device. TI provides a recommended PCB layout in the datasheet and application notes.
Choose input capacitors with low ESR and high ripple current rating. For output capacitors, choose ones with low ESR and high capacitance. The datasheet provides guidelines for capacitor selection, and TI's capacitor selection tool can also be used.
The maximum ambient temperature for the DRV103H is 85°C. However, the device can operate at higher temperatures with derating. Consult the datasheet for thermal derating curves.
Use a voltage supervisor or a voltage monitor IC to detect overvoltage and undervoltage conditions. You can also use a voltage regulator with overvoltage protection to regulate the input voltage to the DRV103H.
Yes, the DRV103H is qualified for automotive and high-reliability applications. It meets the requirements of AEC-Q100 and is manufactured in a facility certified to IATF 16949.
