TIDA-00121: Not getting the HO pulse of the Gate Driver

Part Number: TIDA-00121

Dear Sir/Madam,

We are working on TIDA-00121 Solar Street Light with Integrated MPPT Charger Reference Design Board.

we are getting the PW_H,PW_L (3.3V, f=100KHz) Pulses from the Controller and we are getting LO(10V,f=100KHz) Pulse.but

we are getting 12V DC on HO of the Gate Driver instead of High side Pulse. because of this Battery is Not getting Charged.

Please do the needful for the above.

Thanks & Regards

Gangadhar

  • Hi Gangadhar,

    Please check the connections to the gate driver. Also, try if a change of the gate driver IC solves the issue. Also, please let me know if you have made any changes in the hardware.

    Regards,
