TPS73125-EP: PWM enable pin to facilitate sipping off of battery

Part Number: TPS73125-EP

Good afternoon.....

I am using a high resistive battery source and would like to ramp up my voltage to my sensor through the TPS73125 by PWM the enable pin dynamically (not a fixed PWM).  This will allow me to control the rate at which charge goes into the board and effectively keep my battery from getting 'slugged'.  Can you tell me if I will damage the part at all by doing this?

Thx

  • Hi Steve,

    At what frequency do you plan to PWM the enable pin? What will be the slew rate applied to the enable pin?
  • In reply to Ramesh Khanna:

    Hello Ramesh.....
    The slew rate will most likely be ~10ns (a PWM from an MSP430)....Frequency will be < 10khz

    Thx
    Steve
