MIC2027/2077

Quad USB Power Distribution Switch

General Description

Features

The MIC2027 and MIC2077 are quad high-side MOSFET

switches optimized for general-purpose power distribution

requiring circuit protection. The MIC2027/77 are internally

current limited and have thermal shutdown that protects

the device and load.

• 150mΩ maximum on-resistance per channel

• 2.7V to 5.5V operating range

• 500mA minimum continuous current per channel

• Short-circuit protection with thermal shutdown

• Thermally isolated channels

• Fault status flag with 3ms filter eliminates false

assertions

• Undervoltage lockout

The MIC2077 offers “smart” thermal shutdown that

reduces current consumption in fault modes. When a

thermal shutdown fault occurs, the output is latched off

until the faulty load is removed. Removing the load or

toggling the enable input will reset the device output.

• Reverse current flow blocking (no “body diode”)

• Circuit breaker mode (MIC2077) reduces power

Both devices employ soft-start circuitry that minimizes

inrush current in applications where highly capacitive loads

are employed.

consumption

• Logic-compatible inputs

• Soft-start circuit

• Low quiescent current

A fault status output flag is asserted during overcurrent

and thermal shutdown conditions. Transient current limit

faults are internally filtered.

• Pin compatible with MIC2524 and MIC2527

The MIC2027/77 are available in 16-pin narrow (150 mil)

and wide (300 mil) SOIC packages.
