Part Number: DRV8844 Other Parts Discussed in Thread: DRV8244-Q1 , DRV8243-Q1 , DRV8245-Q1 , Tool/software: Hi,
We are using the DRV8844PWP in our past designs, and now it is getting obsolete. The alternative is DRV8844PWPR but this part is still not AEC…
Part Number: DRV8844 Tool/software: Hi
Regarding DRV8844..
The idea is to trigger an automatic reset in the event of an error (nFault = low) with a small circuit, unfortunately the following information is missing in the data sheet: -) minimum reset time…
Part Number: DRV8844 Tool/software: Could you please help check if there is any problem with the schematic design of DRV8844, thks

Part Number: DRV8844 Tool/software: What could be the reason for Fault being always asserted? Schematic below; I'm trying to simply get the part working, not drive anything yet. V3P3OUT does output 3.3V.
Part Number: DRV8844 Hi team,
How to realize OVP on the output of DRV8844? It seems we do not integrated this kind of protection. Do we have external discrete solution on this?
Part Number: DRV8844 Hi Team,
In datasheet, it is said that the two pins SRC12 and SRC34 of DRV8844 can be connected to external current-limiting resistors, but there is no further specific explanation. Could you possibly help below questions:
1. Is the…
Part Number: DRV8844 Hi Team,
When DRV8844 drives a DC brushed motor in a single channel, it enters protection as soon as it is powered on. After protection, only one output is turned off, and the other output still has PWM output. May I ask why not both…
Part Number: DRV8844 Hi
To use the current sensing function of DRV8844, a circuit is designed and tested As a result of the test, the current is not measured at 0.05 ohm shunt resistance, but the OUTPUT operates In addition, OUTPUT operates even if 0.05…
Part Number: DRV8844 Hi Team,
The customer is using the DRV8844 to drive a DC motor, the IC body is damaged when the motor is running properly. Based on the pictures below, pins 4, 5, 10 and 11 are broken which is VM and OUT. The VM is connected to a 24V…
