The CT3901 is designed to drive 40V~150V VGaNTM, E-type bidirectional GaN HEMT with a single gate and dual drain for low-voltage side battery protection in BMS systems. With its powerful driving capabilities, the CT3901 can drive multiple VGaNTMs in parallel within 50uSec. The input of the 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. The CT3901 has fast opening and closing speeds that respond to fault conditions to protect the system.
