MIC2042/2043  
Single Channel, High Current, Low Voltage,  
Protected Power Distribution Switch  
General Description  
Features  
TheMIC2042andMIC2043arehigh-sideMOSFETswitches  
optimizedforgeneralpurposepowerdistributionapplications  
whichrequirecircuitprotection.Thedevicesswitchupto5.5V  
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, for tighter control over inrush current during  
start-up, the output slew-rate may be adjusted by an external  
capacitor.  
• 60mmax. on-resistance  
• 0.8V to 5.5V operating range  
• Adjustable current limit  
• Power-Good detection  
• Up to 3A continuous output current  
• Short-circuit protection with thermal shutdown  
• Adjustable slew-rate control  
• Circuit breaker mode (MIC2043)  
• Fault status flag  
• Undervoltage lockout  
• Output MOSFET reverse current flow block when  
disabled  
• Very fast reaction to short-circuits  
• Low quiescent current  
The MIC2043 features a auto-reset circuit breaker mode that

lasting more than 28ms. The output is reset by removing or  
reducing the load.
