Technical Details & Description

4V threshold voltage detector with push-pull reset

The ROHM BD46405G-TR is a single-channel voltage detector from the BD46xxx series that monitors a supply rail and asserts an active-low reset when the voltage drops below 4V. The push-pull output stage drives the reset signal without an external pull-up resistor, saving one component per rail. A minimum 45ms reset timeout holds the processor in reset after the supply recovers, giving the oscillator and PLL time to stabilize before code execution starts.

Frequently asked questions

What is the reset timeout of BD46405G-TR?

The reset timeout is 45ms minimum. After the supply voltage rises above the threshold, the reset output remains low for at least 45ms before releasing, giving the system time to stabilize.

What is the output configuration of BD46405G-TR?

The output is push-pull, totem pole, active low. This means the reset signal is driven high and low without needing an external pull-up resistor.
