NCV8876
Automotive Grade
Start-Stop Non-Synchronous
Boost Controller
The NCV8876 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,
protection and thermal shutdown.
Additional features include low quiescent current sleep mode
operation. The NCV8876 is enabled when the supply voltage drops
below 7.3 V, with boost operation initiated when the supply voltage is
below 6.8 V.
Features
⢠Automatic Enable Below 7.3 V (Factory Programmable)
⢠Boost Mode Operation at 6.8 V
⢠$2% Output Accuracy Over Temperature Range
⢠Peak Current Mode Control with Internal Slope Compensation
⢠Externally Adjustable Frequency Operation
⢠Wide Input Voltage Range of 2 V to 40 V, 45 V Load Dump
⢠Low Quiescent Current in Sleep Mode (<11 mA Typical)
⢠CycleâbyâCycle Current Limit Protection
⢠HiccupâMode Overcurrent Protection (OCP)
⢠Thermal Shutdown (TSD)
⢠This is a PbâFree Device
Typical Applications
⢠Applications Requiring Regulated Voltage through Cranking and
StartâStop Operation
