MIC2785

Dual Supply Voltage Monitor

with Manual Reset

General Description

Features

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 (V_IN) separate

from the supply input (V_DD). 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.

• No external components

• Monitors input voltage for under-voltage condition

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

• +1.5% VIN threshold voltage accuracy

• Valid /RST state with VIN down to 0.0V

• Valid /RST state with VDD down to 1.20V

• Factory-programmed 1.62V reference

• Manual reset input (/MR)

The under-voltage detector compares the VIN pin voltage

against the factory-programmed threshold of 1.62V. The

reset output is asserted any time the input voltage drops

below the programmed threshold voltage. A reset can be

generated at any time by asserting the manual reset input,

/MR. This reset output will remain active until the release

of /MR. The /MR input can also be used to daisy-chain the

MIC2785 onto existing power monitoring circuitry or other

supervisors. Hysteresis is included to prevent chattering

due to noise.

• 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

The MIC2785 consumes a minimum of quiescent current,

only 5µA, 1.5µA from the main supply pin and 3.5µA from

the input pin. Offered in a tiny, space saving 6-pin MLF^®

(1.2mm x 1.2mm), package. (RoHS lead-free compliant).

Applications

• Mobile phones

• PDAs

• GPS receivers
