MIC2775 Micrel MIC2775 Micro-Power Voltage Supervisor Final Information General Description Features The MIC2775 is a power supply supervisor that provides • Monitors power supply for under-voltage conditions under-voltage monitoring, manual reset capability, and power- • Choice of factory-programmed thresholds on reset generation in a compact 5-pin SOT package. Fea- • Generates 140ms (minimum) power-on RESET pulse tures include an under-voltage detector, a delay generator, a • Manual reset capability manual reset input, and both active-high and active-low reset • Both active-high and active-low RESET outputs outputs. The under-voltage detector compares VDD against • /RST output valid down to 1.2V a fixed threshold. Ten factory-programmed thresholds are • Ultra-low supply curren
