zDescription

The BD37A19FVM,BD37A41FVM,BD87A28FVM,BD87A29FVM,BD87A34FVM,BD87A41FVM,BD99A41F is a watchdog timer reset IC. 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.

zFeatures

1) High precision detection voltage: ±1.5%, ±2.5% (Ta = −40°C to 105°C)

2) Super-low current consumption: 5 µA (Typ.)

3) Built-in watchdog timer

4) Reset delay time can be set with the CT pin's external capacitance.

5) Watchdog timer monitor time and reset time can be set with the CTW pin's external capacitance.

6) Output circuit type: N-channel open drain

7) Package: MSOP8(BD37A□□FVM,BD87A□□FVM)／SOP8(BD99A41F)

zApplications

All devices using microcontrollers or DSP, including vehicle equipment, displays, servers, DVD players, and telephone systems.
