Micrel MIC2774N-29YM5

多压监控器2.93V，可调2

Overview

The MIC2774 is a dual power supply supervisor that provides undervoltage monitoring, manual reset capability, and power-on reset generation in a compact 5-pin SOT-23 package. Features include two undervoltage detectors, one fixed and one adjustable, and a choice of reset outputs. One undervoltage detector compares VDD against a fixed threshold. Ten factory-programmed thresholds are available. The second, user-adjustable input is compared against a 300mV reference. This low reference voltage allows for the monitoring of voltages lower than those supported by previous supervisor ICs.

• Monitors two independent power supplies for undervoltage conditions• One fixed and one user-adjustable input• Choice of ten factory-programmed thresholds• Adjustable input can monitor supplies as low as 0.3V• Generates 140ms (min.) power-on reset pulse• Manual reset input• Choice of active-high, active-low, or open-drain active-low reset outputs• Inputs may be pulled above VDD (7V abs. max.)• /RST output valid down to 1.2V• Ultra-low supply current, 3.5µA typical• Rejects brief input transients• IttyBitty™ 5-pin SOT-23 package• Pin-compatible upgrade for MAX6306/09/12
