Part Number: DRV8837C Other Parts Discussed in Thread: DRV8837 Hi,
I'm requesting a SPICE model for the DRV8837C 1A Low-Voltage H-Bridge Driver IC.
The datasheet for the IC states the output rise / fall times (p.6) range between 20ns and 188ns (a…
Part Number: DRV8837C
Hi,
1. I would like to know how much of regulation is needed for power inputs Vcc & VM.
I am powering these directly through two Schotty diodes in series from a 3xAAA battery. It also has a 20 mA load other than DRV8837C. …
Part Number: DRV8837C Hi,
Our customers use DRV8837C to drive valve, and VM directly connects to battery about 3.7V. When the valve stalls, the stall current is about 300 mA. As a result, the voltage of battery is pulled down, then MCU resets because…

Naveen,
I am not sure what to make of this. The NOK sample definitely has higher edge rates vs. OK sample, but I am surprised the DRV8837C works OK as those are similar to NOK.
It appears the edges of the DRV8210/2P are much slower.
Have you tried hanging…
Ok, this is what I would expect in terms of logic. If you read my message above again, I wasn't implying that brake is HIZ...HIZ state occurs during deadtime and switching.
Can you please check the part number on the IC? Might be a long shot, but…
Sato,
I have a circuit I used but at the time I verified this the DRV8837C was the cheapest driver that would work. Below are two example circuits. The switches need to be verified for the amount of current required and the input to the digital of the…
Hi Dharmesh,
Your 5 device configuration should work, but appears to need a small edit.
HBRIDGE_OUT3 should not be on U2, and should be moved to U21 to the HBRIDGE_EXTRA location.
The reason is that the solenoid/relay shown connected to U2 HBRIDGE_OUT3…
