Product Overview
NCV887711D1R2G is a non-synchronous boost controller designed to supply a minimum output voltage during start-stop vehicle operation battery voltage sags. The controller drives an external N-channel MOSFET. The device uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver. Protection features include cycle-by-cycle current limiting and Thermal shutdown. Additional features include low quiescent current sleep mode operation. It is enabled when the supply voltage drops below the wake up threshold. Boost Operation is initiated when the supply voltage drops below the regulation set point. Typical application includes applications requiring regulated voltage through cranking and start stop operation.
- Automatic enable below wake up threshold voltage (factory programmable)
- Override disable function, boost mode operation at regulation set point
- ±2% output accuracy over temperature range
- Peak current mode control with internal slope compensation
- Externally adjustable frequency operation
- Wide input voltage range of 2V to 40V, 45V load dump
- Low quiescent current in sleep mode (
12A typical) - Cycle by cycle current limit protection, hiccup mode overcurrent protection
- Thermal shutdown (TSD)
- SOIC−8 package, operating junction temperature range from -40 to 150°C
