Part Number: DRV8770 Tool/software: I am using DRV8770 for Relay driving. Do we need to charge Bootstrap capacitor externally. If not, then how should I configure the IC to charge the Bootstrap capacitor to operate high side MOSFET.
Part Number: DRV8770 Tool/software: Dear Texas Instruments Support Team,
I hope this message finds you well. I am currently working with the DRV8770RGER motor driver and have a few questions regarding its operation. Specifically, my design which is…
Part Number: DRV8770EVM Other Parts Discussed in Thread: DRV8770 , DRV8262 , DRV8262EVM , Tool/software: Hello,
I am investigating a few TI solutions for a new design :
DRV8703 / DRV8262 / DRV8770
I want to drive a 24V BDC boosted to 36V motor …
Part Number: DRV8770 We are trying to design a system with one high frequency leg and one low frequency leg. Using the calculations we are getting about 3uF boostrap capacitor for the 60Hz leg. I know that the bootstrap diode is internal and that it has…
Part Number: DRV8770 Hello,
I am using the driver with the MODE pin tied to GVDD so that I can driver each half-bridge with a single drive signal. However, when powered, I never see that the lower MOSFET gate drives going high (GVDD = 12V in my application…
Part Number: DRV8770 Hi, Good day. In the datasheet it states, "The DRV8770 can drive an H-bridge with power supply up to 100 V." Does that mean the load or motor can see 100Vp-p or 200Vp-p? What is the maximum Low-side drain pin voltage? If I put the…
Part Number: DRV8770 I have an application that frequently experiences catastrophic VBUS shorts when powering up the controller that destroys the MOSFETs and the controller. It appears that the outputs of the gate drivers are open-circuited when in UVLO…
Part Number: DRV8701 Other Parts Discussed in Thread: DRV8251 , DRV8870 , DRV8770
Hello
I am looking for a DC‑motor driver similar to the DRV8701 but with a much higher source/sink capability. The DRV8701 can only handle about 150 mA, and I need…
