0.3A/0.6A, High/Low-Side MOSFET Driver


Update Alert Share

The RT7028A/B is a high-voltage gate driver IC with dual outputs. The IC, together with an external bootstrap network, drives dual n-channel MOSFETs or IGBTs with input voltage rail up to 600V.

The IC is equipped with a "common-mode dV/dt noise canceling technique" to provide high dV/dt immunity which enables stable operation under high dV/dt noise circumstances. Two Under-Voltage Lockout (UVLO) functions continuously monitor the bias voltages on VCC and BOOT-to-LX for preventing malfunction when the bias voltages are lower than the specified threshold voltages. The logic level of the PWM signal input pins are compatible with standard TTL logic level for ease of interfacing with controlling devices.
