Overview
Datasheet Voltage Detectors Voltage Detector ICs with Watchdog Timer BD37Axx Series BD87Axx Series BD99A41F General Description The BD37A19FVM, BD37A41FVM, BD87A28FVM, BD87A29FVM, BD87A34FVM, BD87A41FVM and BD99A41F are watchdog timer reset ICs.
It delivers a high precision detection voltage of ±1.
5% and a super-low current consumption of 5 µA (Typ).
It can be used in a wide range of electronic devices to monitor power supply voltages and in system operation to prevent runaway operation.
Features  Built-in Watchdog Timer  Reset delay time can be set with the CT pin's external capacitance  Watchdog timer monitor time and reset time can be set with the CTW pin's external capacitance.
