            BD37BxxFVM-C/BD87BxxFVM-C/BD87BxxG-C Voltage Detector ICs
                    ROHM voltage detector ICs have a watchdog timer for automotive
    

ROHM BD37BxxFVM-C, BD87BxxFVM-C, and BD87BxxG-C integrate a reset (RESET) that monitors the input voltage of the microcomputer and a watchdog timer (WDT) that monitors the clock signal of the microcomputer. Even with its wide input voltage of up to 20 V, the quiescent current is kept low, making it possible to improve the redundancy of various systems with low current consumption. The RESET detection voltage can be selected from a fixed or variable type by adjusting the external resistor. Also, the external capacitor can adjust the RESET delay time and watchdog monitor time.
