TI simplifies 12V and 24V motor design and provides low-power
FET Integrated Motor Driver Family

TI has launched three brushed DC gate driver products with integrated current sensors. By using the DRV8871 with an integrated current sensor, power loss and heat generation due to the use of external sensor resistors can be reduced, saving costs.

The DRV8871 motor driver family reduces design complexity, power consumption, and board space in end products such as multifunction printers, home appliances, and industrial equipment compared to competing products.

Expanding TI's brushed DC motor driver portfolio, the DRV8871 is one of a number of brushed DC drivers that integrate field-effect transistors (FETs), making it ideal for space-constrained designs. The DRV8870 limits the current across an external current sensor resistor with integrated regulation. Additionally, the DRV8872 enhances system reliability with fault detection monitoring.

As previously mentioned, designing with the DRV8871 reduces system complexity by eliminating individual sensor resistors and saving up to 25% of board space. Furthermore, the absence of sensor routing simplifies board layout by enabling precise current regulation.

Additionally, standard low-cost, low-power resistors are used to set current thresholds. This limits startup and stall/inrush currents and limits current to known levels, significantly reducing system power requirements and the large capacitance required to maintain stable voltage, especially during motor startup and stall conditions.

The DRV8870EVM , DRV8871EVM , and DRV8872EVM evaluation modules (EVMs) demonstrate the functionality and performance of each brushed DC motor driver. Additionally, these EVMs include the TPS7A16 low-dropout regulator (LDO) and the TLC555 low-power timer.
