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. Features • Monitors power supply for under-voltage conditions • Choice of factory-programmed thresholds • Generates 140ms (minimum) power-on RESET pulse • Manual reset capability • Both active-high and active-low RESET outputs • /RST output valid down to 1.2V • Ultra-low supply current, 3.5µA typical • Rejects brief input transients • No external components • Pin compatible upgrade for MAX825 • IttyBitty™ 5-pin SOT-23 package Applications • Monitoring processor core and input/output voltages • Computer systems • PDAs, hand-held PCs • Embedded controllers • Telecommunications systems • Power supplies
