HIP1012A image

The HIP1012A is a HOT SWAP dual supply power distribution controller. Two external N-Channel MOSFETs are driven to distribute power while providing load fault isolation.
At turn-on, the gate of each external N-Channel MOSFET is charged with a 10A current source. Capacitors on each gate (see the Typical Application Diagram), create a programmable ramp (soft turn-on) to control inrush currents. A built in charge pump supplies the gate drive for the 12V supply N-Channel MOSFET switch.

Features
• HOT SWAP Dual Power Distribution Control for +5V and +12V or +5V and +3.3V
• Provides Fault Isolation
• Programmable Current Regulation Level
• Programmable Time Out
• Charge Pump Allows the Use of N-Channel MOSFETs
• Power Good and Overcurrent Latch Indicators
• Enhanced Overcurrent Sensitivity Available
• Redundant Power On Controls
• Adjustable Turn-On Ramp
• Protection During Turn-On
• Two Levels of Current Limit Detection Provide Fast Response to Varying Fault Conditions
• Less Than 1µs Response Time to Dead Short
