The STWLC04JR is a type of power management integrated circuit (PMIC) specialized for providing power to DC motors. It is a motor-driver IC, with integrated full-bridge gate driver and charge pump, as well as current sense circuitry and integrated power FETs. The PMIC comes in a compact form factor, occupying very little printed circuit board (PCB) space, and offers a wide range of features such as adjustable overcurrent protection, optimized motor start-up phase and choke reducing EMI.

Application Field

The STWLC04JR is suitable for a wide range of applications such as office automation, home appliances, automotive products, power tools and small pumps. It is most suitable for use as a DC motor driver, providing power to DC motors. With its integrated power FETs, current sense circuitry, gate driver, and charge pump, it is able to provide high power to the motor efficiently and reliably.

Working Principle

The STWLC04JR uses high and low-side power FETs to deliver power to the DC motor. The low-side FET is driven by the low-side gate driver, while the high-side FET is driven by the high-side integrated charge pump. The integrated current sense circuitry measures the current delivered to the motor and can be used for implementing adjustable over-current protection. The power FETs and gate driver also feature optimized start-up and dead-time parameters to reduce EMI.

The STWLC04JR is a highly integrated PMIC, offering a wide range of features and advantages such as a small form factor, high power efficiency, adjustable over-current protection, and optimized motor start-up phase and dead time to reduce EMI. It is suitable for a range of applications and can be used as a DC motor driver with high efficiency and reliability.
