MIC2776LYM5

General Description

The MIC2776 is a power supply supervisor which provides under-voltage monitoring and power-on reset generation in a compact 5-pin SOT package. Features include an adjustable under-voltage detector, a delay-generator, a manual reset input, and a choice of active-high, active-low, or open-drain active-low reset output. The user-adjustable monitoring input is compared against a 300mV reference. This low reference voltage allows monitoring voltages lower than those supported by previous supervisor ICs.

Features

• User-adjustable input can monitor supplies as low as 0.3V
• ±1.5% threshold accuracy
• Separate VDD input
• Generates power-on reset pulse (140ms min.)
• Manual reset input
• Choice of active-high, active-low or open-drain activelow reset output
• Inputs can be pulled above VDD (7V abs. max.)
• Open-drain output can be pulled above VDD (7V abs. max.)
• Ultra-low supply current, 3.0µA typical
• Rejects brief input transients
• IttyBitty™ SOT-23-5 package

Applications

• Monitoring processor, ASIC, or FPGA core voltage
• Computer systems
• PDAs/Hand-held PCs
• Embedded controllers
• Telecommunications systems
• Power supplies
• Wireless / cellular systems
• Networking hardware
