Product details

Threshold and reset behaviour

The BD73H38G-2CTR is a single-channel voltage detector with a 3.76 V threshold and an active-high reset output. When the monitored supply drops below that threshold, the push-pull output asserts high after a 20 µs minimum reset timeout — fast enough to catch a brownout on a 100 kHz clocked rail without false triggering on supply ripple.

Package and temperature grade

Housed in a 5-pin SC-74A (SOT-753) package, it is a surface-mount part with a 5-SSOP supplier device package designation.

Frequently asked questions

What is the reset polarity and output type of BD73H38G-2CTR?

The reset is active high, and the output is push-pull (totem pole). This means the output drives high when the monitored voltage falls below the 3.76 V threshold, and it does not require an external pull-up resistor.

What package does BD73H38G-2CTR come in?

It is supplied in a 5-pin SC-74A (SOT-753) surface-mount package, also designated as 5-SSOP. Available in tape and reel or cut tape options.
