MIC2775集成电路（IC）的监控器规格书PDF中文资料

General Description

The MIC2775 is a power supply supervisor that provides under-voltage monitoring, manual reset capability, and power-on reset generation in a compact 5-pin SOT package. Features include an under-voltage detector, a delay generator, a manual reset input, and both active-high and active-low reset outputs. The under-voltage detector compares VDD against a fixed threshold. Ten factory-programmed thresholds are available.
