MIC2774

Dual Micro-Power Low Voltage Supervisor

General Description

Features

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 V_DDagainst

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 V_DD(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

The reset outputs are asserted at power-on and at any

time either voltage drops below the programmed threshold

voltage and remains asserted for 140ms (min.) after they

subsequently rise back above the threshold boundaries.

Manual reset functionality can be provided by a switch

connected between ground and the /MR input. A wide

choice of voltage thresholds provides for a variety of

supply voltages and tolerances. Hysteresis is included to

prevent chattering due to noise. Typical supply current is a

low 3.5µA.

Applications

• Monitoring processor ASIC or FPGA core and I/O

voltages
