MIC2310  
Single-FET, Constant Power-Limit Hot  
Swap Controller  
General Description  
Features  
The MIC2310 is a single-channel, positive voltage,  
constant power-limit hot swap controller designed to  
provide for the safe insertion and removal of pc boards into  
fixed, rack, and pedestal mid- or back-planes using few  
external components. In addition, the MIC2310 employs a  
patent-pending, output load power-limiting technique  
where the current limit is inversely proportional to the  
output load voltage, such that the power product will not  
exceed the programmed power limit any longer than the  
externally programmed primary overcurrent period. The  
MIC2310 is ideally suited to address the power-limiting  
and timing requirements per the UL60950 specification for  
240-VA applications. The MIC2310 incorporates high-side  
controller circuitry for an external N-channel MOSFET for  
which the MOSFET drain current rate of change is user-  
programmable via an external capacitor. The MIC2310  
employs dual-speed, dual-level overcurrent fault  
protection. The primary overcurrent detector response time  
is programmable via an external current sense resistor and  
the secondary overcurrent detector is 2-bit user-  
programmable and exhibits a very fast (default) response  
to faults to ensure that the system power supplies are  
protected against catastrophic load current and short-  
circuit faults. Additionally, an analog output (voltage) signal  
is provided that is proportional to the steady-state load  
current to allow monitoring of the system’s power. A  
PWRGD signal is provided to indicate a valid output  
voltage that can be used to enable a DC-DC power  
module.  
Provides safe PCB insertion and removal from live  
+12V backplanes  
Patent-pending, adaptive circuit breaker threshold  
control  
Maintains constant power product at output  
Power-limit product (VA) is externally  
programmable for various power applications  
Dual-level, dual-speed overcurrent detection/protection  
Programmable primary detector response time  
Fast (< 1 µs) secondary detector response time to  
short circuit conditions  
ƒ User-programmable threshold settings via (2)  
digital inputs  
Steady-state load current monitoring  
Programmable inrush current slew-rate control  
Electronic circuit breaker functions after fault
