DRV101FKTWT is a low-side power driver launched by TI, specifically designed for driving valves, solenoid valves, relays, and other inductive or resistive loads. It adopts a 7-pin DDPAK/TO-263 surface mount packaging. This chip integrates PWM control, power output, and protection functions into one, suitable for industrial scenarios that require precise power control and low heat generation.
Its main performance parameters are: working voltage range 9V to 60V, maximum output current 1.9A. It internally integrates a 24kHz PWM oscillator, and the duty cycle can be adjusted through an external resistor to achieve the "strong pull-in - weak hold" mode to reduce power consumption and heat generation. It has adjustable delay function, supports overcurrent/undercurrent detection and overheat shutdown protection, and provides status flag output.
