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
