MIC2045 - Protected Power Distribution Switch

This page provides the datasheet information for the MIC2045, a member of the MIC2044 Protected Power Distribution Switch family.

Description

The MIC2044 and MIC2045 are high-side MOSFET switches optimized for general purpose power distribution applications that require circuit protection.

Features

  • a auto-reset circuit breaker that latches the output OFF upon detecting an overcurrent condition lasting more than 32ms. The output is reset by removing or reducing the load. Data sheets and support documentation can be found on Micrel’s web site at www. micrel. com. Features.
  • 30mΩ maximum on-resistance.
  • 0.8V to 5.5V operating range.
  • Adjustable current limit.
  • Up to 6A continuous output current.
  • Short circuit protection.
  • Very fast reaction to s.

MIC2044/2045 Micrel MIC2044/2045 Single Channel, High Current, Low Voltage, Protected Power Distribution Switch General Description The MIC2044 and MIC2045 are high-side MOSFET switches optimized for general purpose power distribution applications that require circuit protection. These 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 to indicate 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, for tighter control over inrush current during start up, the output slew-rate may be adjusted by an external capacitor.
