Working Principle
The TC4626EPA is designed to meet the needs of digital logic level applications. It is an efficient gate driver, which monitors the logic level applied to the input to control the output voltage and current level. This device features a power circuit which can detect the input logic level, quickly charging and discharging the output device’s gate voltage via MOSFETs. The input circuit is further enhanced by a comparator which serves two purposes: detecting the logic level and driving the MOSFET in the power stage.

The CT4626EPA utilizes a bridge configuration made of two N-channel and two P-channel MOSFETs. These MOSFETs are capable of driving up to 6A at 12V. The four MOSFETs help to protect the output device from short-circuiting, over current, over voltage and two-phase fault conditions. In addition, the device is able to dynamically adjust the output voltage level, once the input logic level has been determined.

The TC4626EPA offers the maximum power supply efficiency and reliability while maintaining the low power consumption and low operating cost.
