MIC2026A/76A

Dual-Channel Power Distribution Switches

Features

General Description

• 100 mΩ Typical R_DS(ON)at 5.0V

• 140 mΩ Maximum R_DS(ON)at 5.0V

• 2.7V to 5.5V Operating Range

The MIC2026A and MIC2076A are high-side MOSFET

switches optimized for general-purpose power

distribution that require circuit protection. The

MIC2026A is particularly well suited for USB

applications.

• 500 mA Minimum Continuous Current per

Channel

The MIC2026A/76A are internally current limited and

have thermal shutdown that protects the device and

load.

• Short-Circuit Protection with Thermal Shutdown

• Thermally Isolated Channels

• Soft-Start Circuit

The MIC2076A offers smart shutdown that reduces

current consumption in fault modes. When the

MIC2076A goes into thermal shutdown due to current

limiting, the output is latched off until the switch is reset.

The MIC2076A can be reset by removing the load,

toggling the enable input or cycling V_IN.

• Fault Status Flag with 3 ms Filter Eliminates False

Assertions

• Undervoltage Lockout (UVLO)

• Reverse Current Flow Blocking (No “Body Diode”)

• Circuit Breaker Mode (MIC2076A)

• Pin Compatible with MIC2026 and MIC2076

• Logic-Compatible Inputs

Both devices employ soft-start circuitry that minimizes

inrush current in applications where highly capacitive

loads are employed.

• Low Quiescent Current

A fault status output flag is asserted during overcurrent

or thermal shutdown conditions. Transient faults are

internally filtered.

Applications

• USB Peripherals

• General Purpose Power Switching

• ACPI Power Distribution

• Notebook PCs

The MIC2026A and MIC2076A are available in an 8-pin

SOIC package.

• PDAs

Package Type

• PC Card Hot Swap
