Boost Controller

NCV8876

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)

• Cycle−by−Cycle Current Limit Protection

• Hiccup−Mode Overcurrent Protection (OCP)

• Thermal Shutdown (TSD)

• This is a Pb−Free Device

• NCV Prefix for Automotive and Other Applications Requiring

Unique Site and Control Change Requirements; AEC−Q100

Qualified and PPAP Capable

Typical Applications

• Applications Requiring Regulated Voltage through Cranking and

Start−Stop Operation
