Voltage Detector ICs with Watchdog Timer

BD37Axx Series

BD87Axx Series

BD99A41F

●General Description

●Key Specifications

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.
