The DRV8244SQDGQRQ1 from Texas Instruments is a fully integrated H-Bridge driver designed for automotive applications. It supports a wide operating voltage range from 4.5V to 35V, with an absolute maximum of 40V. This device can deliver a peak output current of 21A and features integrated current sensing, eliminating the need for an external shunt resistor.
Key electrical specifications include a low on-resistance (RON_LS + RON_HS) of 47 mΩ in the VQFN-HR package and 60 mΩ in the HVSSOP package. It operates with PWM frequencies up to 25 KHz and supports 3.3V and 5V logic inputs. The device offers a low sleep current of 1μA typical at 25°C.
This H-Bridge driver is AEC-Q100 qualified for automotive applications, with an operating temperature range of -40°C to 125°C. It provides various protection and diagnostic features, including over-current protection, over-temperature protection, and load diagnostics. The DRV8244SQDGQRQ1 is available in variants with SPI or hardwired interfaces, offering flexibility in control and configuration.
It is suitable for driving automotive brushed DC motors and solenoids in applications such as door modules, wiper modules, trunk and seat modules, body control modules, steering systems, gas engine systems, and on-board chargers. The device is available in a 28-HTSSOP surface mount package.
