The DRV8870DDAR is a Brushed DC motor driver manufactured by Texas Instruments for a wide operating voltage range of 6.5V to 45V. DRV8870DDAR chip can provideup to 3.6A peak current, support PWM (pulse width modulation) control interface, with integrated current regulation function. The DRV8870DDAR features a low-power
sleep mode and a small package size, specifically an 8-pin HSOP with a PowerPAD. The DRV8870DDAR motor driver chip also features a variety of protection features,
including undervoltage lockout (UVLO), overcurrent protection (OCP), thermal shutdown (TSD), and automatic fault recovery. The DRV8870DDAR is used in a wide range
of applications, including printers, electrical appliances, industrial equipment and other mechatronics applications.
DRV8870DDAR Features:
- DRV8870DDAR has independent H-bridge motor drive capability to drive a DC motor, a stepper motor winding or other loads.
- RDS(on) (HS + LS) with 565 Mω (typical value), which helps to improve motor drive efficiency.
- The control mode of the chip is PWM and is controlled through the hardware (GPIO) interface.
- Integrated current regulation allows current limiting based on analog input VREF and ISEN pin voltages to reduce system power requirements.
- The sleep current in sleep mode is 10µA, helping to extend battery life in low-power applications.
- Package size is 4.9mm x 6.0mm, suitable for space-constrained applications.
DRV8870DDAR application:
The DRV8870DDAR is suitable for a variety of applications that require precise motor control, such as printers, household appliances, industrial equipment, etc. It can be
used to drive and control the position of brush DC motors to achieve accurate motor position control. Due to its integrated protection features, it is also suitable for
applications where motor operation safety is required.
The DRV8870DDAR chip is a preferred solution for motor drives with its efficient motor control capabilities, integrated current regulation and protection features, and
flexibility for a wide range of application scenarios.
