Part Number: DRV8837 Hello
I use drv8837 on our board.
Our board operates the Motor Linear Actuator. (Motor Model : xydh12)
Our board performs break operation after forward or reverse operation.
When breaking, the motor generates twice as much (about…
Part Number: DRV8837 Hi,
I have connected nSLEEP, IN1, IN2 to the controller GPIO's. Everything is working fine but when I check the current that my circuit draws when nSLEEP = 0, it shows 1.1mA (exclusive of other peripherals on board). The datasheet…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8838 , , DRV8873-Q1 , Hi,
There are two questions regarding DRV8837/DRV8838 motor driver IC.
1. I did a simple test in LTspice using DRV8837. I set In1 to 0V and IN2 to 3.3V. I expect to see a DC signal…
Part Number: DRV8837 Hello,
I am performing low-side current measurement for the motor fault detection. As shown in the attached image, in left side I was using transistor for motor bridge and 0.1 Ohm resistor for motor current failure detection.
But…

Dear team,
May I double confirm with you about below delay time of each mode switch?
Mode Switch
Delay time
Forward to Coast
output disable time: T8
Forward to Brake
output high to low: T12
Reverse to Coast

Part Number: DRV8837 Hi
I am working on a large volume project for a client. Due to the FDA approval I need to go into details with the H-Bridge. I have downloaded the newest (and only) PSpice model DRV8837 PSpice Model (Rev. A) "SLVM958A.ZIP (18 KB) - PSpice…
Part Number: DRV8837 Hello,
Is it required to connect a varistor or birectional TVS diode in parallel to motor for protection against high voltage spikes? or does the IC provides protection against inductor current?
Part Number: DRV8837 Hi,
Customer want to know the internal connection of thermal pad. what if they don't connect that with GND and let it floating? thanks.

Part Number: DRV8837 I've incorporated a DRV8837 into my motor application. VM is supplied by a boost regulator that maintains an output of 7V.
When I drive the motor and then abruptly brake, I see the expected negative flyback current coming from…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8833 Hi there,
we are considering use DRV8837 to control DC motor, simply in open loop. Some questions on H bridge and PWM control basics.
Question 1: In datasheet figure 11, the motor is running…
