General Description

The MIC2785 is a micropower voltage monitor that provides under-voltage monitoring and manual reset

capability in a tiny 1.2mm x 1.2mm MLF® package. The MIC2785 provides a monitored voltage input (VIN) separate from the supply input (VDD). This insures that the reset (/RST) output maintains a valid output state when the voltage being monitored ramps up or down. The device also includes a manual reset input (/MR). The /RST output is an active low push-pull output.

Features

• No external components

• Monitors input voltage for under-voltage condition

• Separate inputs for supply (VDD) and monitor (VIN)

• Factory-programmed 1.62V reference

• Manual reset input (/MR)

• Active low RESET (/RST) output

• Ultra-low input current – 5µA total (VIN and VDD)

• Rejects brief input transients

• -25°C to 85°C operating temperature range

• RoHS lead-free compliant

• Available in tiny 6-pin 1.2mm x 1.2mm Thin MLF® package

Applications

• Mobile phones
