BMS single-phase enhanced GaN half bridge chip

CT3901

100V low-voltage bidirectional VGaN driver

 Product Introduction 

CT3901 is designed to drive a 40V~150V VGaNTM, E-type bidirectional GaN HEMT with a single gate and dual drain, used for low-voltage side battery protection in BMS systems. With its powerful driving capability, CT3901 can drive multiple VGaNTMs in parallel within 50uSec. The input of CT3901 is compatible with AFE/MCU logic and can withstand input logic voltages up to 20V. CT3901 is a dedicated driver for CT-UNITE 40V~150V VGaNTM, with a gate drive voltage of 5V. CT3901 has fast turn-on and turn off speeds and can respond to fault conditions to protect the system.
