System reset IC
BH6150F
The BH6150F has two reset circuits, one detects the power supply voltage, and the other detects the input voltage.
With this one IC it is possible to apply a reset to the logic systems of CPUs, and mechanical systems.
Applications
Personal computers, CPUs, MPUs, logic circuits, reset
circuits for mechanical systems, level detector circuits,
battery voltage detector circuits, and backup power
supply switching circuits
Features
Two types of reset circuit provided.
1) Reset circuit 1 (input voltage detector)
Detection voltage: 1.25V (Typ.)
Transmission delay time: 200µs (Typ.)
Open collector output, and 10kpull-up resistor on
chip.
2) Reset circuit 2 (supply voltage detector)
Detection voltage: 4.2V (Typ.)
Transmission delay time: 25, 50, 100 and 200 ms
(select using the Ct0 and Ct1 pins)
Manual reset function provided
Open collector output, and 10kpull-up resistor on
chip.
Absolute maximum ratings (Ta = 25°C)
