Frequently Asked Questions
What continuous output current can PDRV8243HRXYQ1 deliver in a 12 V automotive motor drive circuit?
PDRV8243HRXYQ1 supports up to 3 A continuous output current when driving DC brush motors or solenoids from a 12 V automotive supply. Cycle-by-cycle overcurrent protection and thermal shutdown at approximately 150 °C safeguard both the device and the connected load during fault conditions, reducing the need for external protection components.
How does the integrated current sense in PDRV8243HRXYQ1 simplify automotive actuator board design?
The integrated current sense eliminates the need for an external shunt resistor, saving PCB space and reducing BOM cost in compact actuator modules. The measured current value is available via SPI, enabling the host MCU to implement closed-loop current control or diagnostics without additional analog signal conditioning circuits — a significant advantage in 12 V body-control designs with tight layout budgets.
Which fault conditions does PDRV8243HRXYQ1 detect and report for ASIL-B functional safety compliance?
The device detects and reports open-load, short-to-ground, short-to-supply, over-temperature above 150 °C, and undervoltage conditions through its SPI diagnostic register. This fault coverage supports functional safety monitoring at ASIL-B level under ISO 26262, making it suitable for automotive seat, mirror, and window actuators that must demonstrate safe-state handling within defined reaction times.
