MIC2040/2041 Micrel MIC2040/2041
Single Channel Low Voltage Power Distribution Switch General Description Features The MIC2040 and MIC2041 are high side MOSFET switches
optimized for general purpose power distribution applications
that 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.
Additionally, the MIC2040/41 is suited for multi-port USB
applications to satisfy upstream/downstream power requirements.
The MIC2041 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 load.
