Hi Chris,
Adding to Yanming's comment, the TPA3255 can drive this device but the input control is an analog signal rather than a PWM input like the DRV595. It also can only get up to 600kHz switching frequency on the output FETs.
Best Regards,

Part Number: DRV595 Hi team,
For the DRV595, what's the maximum differential output voltage?
Does the maximum differential output voltage relate to the supply voltage and the load?
I have find the spec in the datasheet, the datasheet shows the output…
Part Number: DRV595 Hi team,
My customer use the DRV595 as a TEC driver.
Below is the schematic.
The purple means not install.
So after power on the device, they will use the MCU to pull the SDZ to high.
if the voltage between the IN+ and IN- is 1V,…
Part Number: DRV595 Dear team,
Here is a question about DRV595.
Our customer use this chip in a TEC application. When they do the low temperature test, they found that if they put the chip(DRV595) and the TEC element into the cold temperature(about -…
Part Number: DRV595 Hi Team,
can you please give me the equations about how PWM duty cycle can be calculated for DRV595 in both (1spw, bd) modulations?
Thanks and Regards,
Mihir
Part Number: DRV595 HI Team, see attachment- we are also wondering the data sheet impiles that the input pins are biased at 3V ( says biased rathre then bias) and also
DIFFERENTIAL OR SINGLE-ENDED INPUTS The differential input stage of the amplifier cancels…
Hi Shawn,
Because of the PCB size limitation, customer consider to parallel two TECs and use the one DRV595.
Does this solution has feasibility?
Lacey
Thanks a lot!
Part Number: DRV595 Other Parts Discussed in Thread: DRV2511-Q1 , Hi, what are the differences between DRV595 and DRV2511-Q1 which is 10x cheaper? are the two parts compatible?
Part Number: DRV595 I'm looking at using the DRV595 for a peliter application. If I understand the data sheet I can use the single ended output (0-2.7V) from a DAC on the IN+ input and bias the IN- output to about 1.4V.
Does this mean that with the…
Part Number: DRV595 Hello,
I am using drv595 to drive a peltier 12V/7A. I have used the standard schematic given by ti. Fault and SDZ pin is shorted and pulled up.
Freq =500KHz (FS0= high, FS1= LOW, FS2=LOW)
MODSEL PIN = LOW, Master Mode selected, Gain…
