Other Parts Discussed in Thread: DRV8702-Q1, DRV8703-Q1
Hi all,
My customer is seeking a motor driver solution from TI. I only found the DRV870x solution from ti.com ,but the PWM frequency is fixed. (100kHz)
He would like to operate in 20 kHz to reduce switching loss and heat. Below information is the application background. Could anyone recommend the corresponding solution including motor drivers and external MOSFET ? Thank you for your help.
Background:
Application : Automotive (PTG motor driver)
Topology : H-Bridge
Maximum load current : 15A/30A
switching frequency : 20 kHz
input voltage : 9-16V
test condition : Vin=18V / an hour / 85 Celsius degree
Vin=26V/2 min / 85 Celsius degree
ISO7637 pulse5b 40V/400ms/0.5Ω
