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.
Output Circuit Type: N-Channel Open Drain
