MIC2043 - Protected Power Distribution Switch

Download the MIC2043 datasheet PDF. This datasheet also covers the MIC2042 variant, as both devices belong to the same protected power distribution switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The MIC2042 and MIC2043 are high-side MOSFET switches optimized for general purpose power distribution applications which require circuit protection.

Key Features

  • a auto-reset circuit breaker mode that latches the output off upon detecting an overcurrent condition lasting more than 28ms. The output is reset by removing or reducing the lo.

MIC2042/2043 Micrel MIC2042/2043 Single Channel, High Current, Low Voltage, Protected Power Distribution Switch General Description The MIC2042 and MIC2043 are high-side MOSFET switches optimized for general purpose power distribution applications which require circuit protection. The devices switch up to 5.5V and as low as 0.8V while offering both programmable current limiting and thermal shutdown to protect the device and the load. A fault status output is provided in order to detect overcurrent and thermal shutdown fault conditions. Both devices employ soft-start circuitry to minimize the inrush current in applications that employ highly capacitive loads.
