MIC2026/2076

Dual-Channel Power Distribution Switch

General Description

Features

The MIC2026 and MIC2076 are high-side MOSFET

switches optimized for general-purpose power distribution

requiring circuit protection.

• 140mΩ maximum on-resistance per channel

• 2.7V to 5.5V operating range

• 500mA minimum continuous current per channel

• Shortcircuit protection with thermal shutdown

• Thermally isolated channels

The MIC2026/76 are internally current limited and have

thermal shutdown that protects the device and load.

The MIC2076 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.

• Fault status flag with 3ms filter eliminates false

assertions

• Undervoltage lockout

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

• Circuit breaker mode (MIC2076)

• Logic-compatible inputs

• Soft-start circuit

• Low quiescent current

• Pin compatible with MIC2526

• UL File # E179633

Both devices employ soft-start circuitry that minimizes

inrush current in applications where highly capacitive loads

are employed.

A fault status output flag is asserted during overcurrent

and thermal shutdown conditions. Transient faults are

internally filtered.

The MIC2026/76 are available in 8-pin DIP or 8-pin SOIC.
