ZL50061GAG

Application Fields

The ZL50061GAG can be employed as an interface in motor driver and power conditioner applications used in HVAC, appliances, and industrial equipment, among others. It is also used for controlling half bridge power stages in inverter topologies and to interface with commutation logic in traction applications. In general, the device is used to provide high-performance, insulated gate drive capability in any application that requires insulated gate bi-directional control with isolator protection.

Working Principle

The ZL50061GAG is based on an optically-isolated gate drive topology that utilizes a high-performance, high-efficiency LED and a target photodiode as the communication interface between input and output. It has an isolation rating of 4.0 kV and a direct-drive output current of 5A. It communicates with the IGBT gate driver stage through an IGBT-specific, CANEXT based input signal protocol. In addition, the device features a linear optocoupler Darlington structure for linear speed control and a multi-level PWM signal for operating the IGBTs in a high temperature range.

The ZL50061GAG features current-limiting and over-temperature protection, allowing for reliable and safe operation in critical industrial environments. Additionally, it supports up to 16 levels of PWM signal outputs and full input signal isolation. This provides the flexibility required to support a wide range of power stages and gives the opportunity to reduce power dissipation and power consumption.
