Part Number: DRV8844 Dear TI: My customer used DRV8844 to ouput a sine wave driver, the schematic as below:
First, customer set 100% duty PWM to DRV8844, the sine waveform output is OK, but when duty ratio is adjusted to 90% by MCU online, the sine waveform…
Part Number: DRV8844 Hi,
I'm using the DRV8844 to drive a single DC brushed motor, so I'm connecting the outputs in parallel to increase the available current (as discussed here ). I have OUT1/2 shorted and OUT3/4 shorted, and same for IN1/2, EN1…
Part Number: DRV8844 This is a continuation of investigation about this issue:
So I added an external 2Amp diode (Ifsm=150A) in parallel to the internal free wheeling diode from OUT to VM to have…
Part Number: DRV8844 Dears,
My customer design with DRV8844 for their product but found DRV8844 damaged often.
Attached is the schematics.
The PW1 is 48V~50V.
Can you help to review it and give me some idea for modification?
Part Number: DRV8844 Hi Team,
The customer is experiencing below issue and needs your help.
The application circuit is shown in the figure above. DRV8844PWP is very hot when 24V positive and negative terminals are connected to VCC24V and GND respectively…
Part Number: DRV8844 Hi, Team
Customer reported IC failure when doing outputs direct short test on DRV8844.
DRV8844 is plugged to +/-24V power supply and drive 4 bi-directional solenoids.
>20A peak current was captured from current waveform. IC was damaged…
Part Number: DRV8844 Hi team.
I'd like to know about the operation when the protection.
If OCP or Short Circuit Protection occurs, does the device stop all systems?
Or does it stop only the channel where protection occurred?
Part Number: DRV8844 I am working on a 36V application and will work on 48V as well. I am driving a PAR36 LED Flood light for Forklift equipment. The LED Flood light has steady state current of 0.5A @ 36V but inrush can be as high as 10A in microseconds…
