PMIC - Gate Drivers

The 6EDL04I06NTXUMA1 is a fully integrated power management integrated circuit (PMIC) with the primary purpose of providing gate drivers for high-side and low-side power MOSFETs and IGBTs for a broad range of general-purpose motor applications. It can drive both high-side and low-side transistors and features integrated over-voltage and over-current protection, current and voltage sense detection, programmable dead-time control, over-temperature protection and open-drain output drivers. It is designed to operate over a wide input voltage range and provides a high-level of control and speed performance.

Application Field

The 6EDL04I06NTXUMA1 is suitable for a wide range of general-purpose motor control applications, including brushless DC (BLDC) motors, stepper motors, permanent magnet synchronous motors (PMSM) and AC induction motors (ACIM). It can be used in a variety of industrial applications such as pumps, fans, compressors and conveyors. It is also suitable for use in distributed power systems, alternative energy systems and automotive applications such as electric and hybrid electric vehicles.

Working Principle

The 6EDL04I06NTXUMA1 operates with high reliability by actively monitoring the input voltage and controlling the gate drivers. It contains two independent high-performance gate drivers that can be configured to drive both upper and lower MOSFETs/IGBTs at the same time, or alternatively, just one of the two power devices. The gate drivers are integrated with a slew rate or damping control circuit which allows the user to program a desired slew rate of the gate voltage waveform to meet design requirements. The 6EDL04I06NTXUMA1 also provides a programmable dead-time control for regulating the minimum delay between the upper and lower gate drives by setting the desired dead-time period. This feature helps to reduce the voltage cross over at the switches.

The 6EDL04I06NTXUMA1 also contains integrated over-voltage and over-current protection circuits that protect the power devices from excessive power supply voltages or current. It also features over-temperature protection, programmable input over-voltage protection, and an open-drain output driver. The over-temperature protection system prevents the device from being damaged due to excessive operating temperatures and shuts off the device when the temperature reaches a certain limit. The open-drain output driver allows the user to control the logic state of the device using an external control signal.

The 6EDL04I06NTXUMA1 also contains a current and voltage sense amplifier which allows the user to detect the output current and voltage of each MOSFET and IGBT. This feature helps the user to accurately monitor and control the outputs for optimum performance and maximum efficiency. The 6EDL04I06NTXUMA1 also contains an integrated fast-start circuit which helps to reduce the start-up time and provide a smooth start-up in a very short time.

The 6EDL04I06NTXUMA1 is designed to operate over a wide input voltage range and allows the system designers to reduce the number of components in their motor-control designs, thus reducing overall system cost. It also provides extreme flexibility in terms of the control and speed performance, making it suitable for a broad range of applications.
