Working Principle

EL7457CL-T7 devices operate on the principle of driving high magnitude gate signals from a variety of supply rails. The devices have logic level inputs and an adjustable drive current from 5 mA to 200 mA. When a logic level input is applied, the device will drive the gate signal high or low depending on the input level. The rise and fall times of the gate signal are adjustable via the external circuit. In addition, the pick-off threshold of the device is adjustable to prevent false triggering of the device.

EL7457CL-T7 devices also provide protection from over-voltage, under-voltage and current overload conditions. This protection is achieved through the use of an adjustable current sense voltage, which is derived from an internal sense resistor. The current sense voltage is compared to an adjustable trip point, and if it exceeds the trip point, the device will shut off the gate signal and latch in this state until a fault condition is cleared. This feature ensures reliable operation of the device.

Conclusion

EL7457CL-T7 is a family of PMIC gate drivers that offer high speed, reliability, and proven field performance. These devices feature adjustable output drive current and adjustablerise and fall times, as well as over-voltage, under-voltage and current overload protection. The wide temperature range, high peak output current and low power consumption make EL7457CL-T7 devices ideal for a wide range of applications, including motor drives and robotics, telecom equipment, HVAC systems, medical instrumentation, industrial automation, and automotive applications.
