MIC2090/1

Current-Limiting Power Distribution Switches

Features

General Description

• 1.8V to 5.5V Supply Voltage

The MIC2090 and MIC2091 are high-side MOSFET

power switches optimized for general purpose 50 mA

or 100 mA low power distribution in circuits that require

overcurrent limiting and circuit protection. Typical

applications for these parts include switching power in

USB ports, portable consumer items, camera and

camcorder motor protection, thermal printer head

protection, and many other low current-load switching

applications.

• 790 mΩ Typical R_DS(ON)at 3.3V

• MIC2090 is Rated for 50 mA Minimum

Continuous Current

• MIC2091 is Rated for 100 mA Minimum

Continuous Current

• Reverse Current Blocking (OGI)

• 20 ns Super Fast Reaction Time to Hard Short at

Output

The MIC2090 and MIC2091 come in two versions:

auto-retry current-limit and output latch off on an

overcurrent fault. The MIC2090 and MIC2091 are

offered in a space saving 5-pin SOT-23 package with

an operating junction temperature range of –40°C to

+125°C.

• 10 ms Fault Flag Delay (t_{D_FAULT/}) Eliminates

False Assertions

• Auto-Retry Overcurrent and Short-Circuit

Protection (-1 Version)

• Latch-Off on Current-Limit (-2 Version)

• Thermal Shutdown

• Fault Status Flag Indicates: Overcurrent,

Overtemperature, or UVLO

Package Type

• Undervoltage Lockout (UVLO)

• Low Quiescent Current
