General Description
The ML61 is a group of high-precision and low-power voltage detectors.
The ML61 consists of a highly-accurate and low-power reference voltage source, a comparator,
a hysteresis circuit, and an output driver. Detect voltage is very accurate and stable with
N-channel open drain and CMOS, are available.
