The DRV8245HQRXZRQ1 from Texas Instruments is a fully integrated H-bridge driver designed for automotive applications. It supports a wide operating voltage range of 4.5V to 35V, with an absolute maximum rating of 40V, and can handle a peak output current of 32A. This device features integrated current sensing, eliminating the need for an external shunt resistor, and provides proportional load current output.
Key electrical specifications include a low on-resistance (RON_LS + RON_HS) of 32 mΩ for the VQFN-HR package and 40 mΩ for the HTSSOP package. It operates with PWM frequencies up to 25 KHz and supports 3.3V and 5V logic inputs via PWM or SPI interfaces. The driver includes comprehensive protection and diagnostic features such as over-current protection, over-temperature protection, and load diagnostics for open load and short circuits.
Designed for automotive environments, the DRV8245HQRXZRQ1 is AEC-Q100 qualified with a temperature grade of 1 (–40°C to +125°C). It is available in a 16-pin VQFN-HR package with surface mount mounting type. The device also offers a low sleep current of 1μA typical at 25°C, contributing to power efficiency in standby modes. Documentation is available to aid in functional safety system design.
