MIC2027/2077  
Quad USB Power Distribution Switch  
Preliminary Information  
General Description  
Features  
The MIC2027 and MIC2077 are quad high-side MOSFET  
switches optimized for general-purpose power distribution  
requiring circuit protection. The MIC2027/77 are internally  
current limited and have thermal shutdown that protects the  
device and load.  
140mmaximum on-resistance per channel  
2.7V to 5.5V operating range  
500mA minimum continuous current per channel  
Short-circuit protection with thermal shutdown  
Thermally isolated channels  
Fault status flag with 3ms filter  
eliminates false assertions  
Undervoltage lockout  
Reverse current flow blocking (no body diode)  
Circuit breaker mode (MIC2077)  
reduces power consumption  
Logic-compatible inputs  
Soft-start circuit  
Low quiescent current  
The MIC2077 offers “smart” thermal shutdown that reduces  
current consumption in fault modes. When a thermal shut-  
down fault occurs, the output is latched off until the faulty load  
is removed. Removing the load or toggling the enable input  
will reset the device output.  
Both devices employ soft-start circuitry that minimizes inrush  
current in applications where highly capacitive loads are  
employed.  
A fault status output flag is asserted during overcurrent and  
thermal shutdown conditions. Transient current limit faults  
are internally filtered.  
Pin-compatible with MIC2524 and MIC2527  
Applications  
USB peripherals  
The MIC2027/77 is available in narrow (150 mil) and wide  
(300 mil) SOP (small outline packages).
