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.
Features
• 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
Applications
• Monitoring processor ASIC or FPGA core and I/O voltages
• PDAs, hand-held PCs
• Embedded controllers
• Telecommunications systems
• Power supplies
• Wireless/cellular systems
• Networking hardware
