Overview
The DRV8803PWPR from Texas Instruments is a quad low-side driver IC designed for driving various types of loads, including unipolar stepper motors, DC motors, relays, and solenoids. This device features four protected low-side drivers with integrated overcurrent protection, short circuit protection, undervoltage lockout, and overtemperature protection. The DRV8803PWPR is available in a 16-pin HTSSOP (PWP) package and supports a wide operating supply voltage range of 8.2V to 60V.
The device is controlled through a simple parallel interface and includes integrated inductive clamp diodes to manage turnoff transients generated by inductive loads. It also features a fault output pin to indicate any protection faults. The DRV8803PWPR is suitable for applications requiring robust and reliable low-side switching with advanced protection features.
