EL7154CN is a 3-channel high-speed low-side gate driver IC designed for applications with power MOSFET and IGBT outputs. This IC can be used in any application where three outputs are needed from a single supply, such as DC motors, power converters, and other power applications. The EL7154CN is unique in that it offers three output channels in a single package, allowing for a much more compact design than other devices with multiple output channels.

Application Field

EL7154CN is a PMIC - Gate Drivers and can be used in applications where the control of three outputs is needed from a single supply – DC motors, power converters and other power applications. It comes with integrated diagnostic features, such as open and out-value outputs, as well as an overdraw status flag. The EL7154CN can be used in many applications, including but not limited to automotive, industrial and consumer electronics.

In automotive applications, the EL7154CN can be used to control DC motor drives, power steering, and suspension applications. In industrial applications, it can be used for pump, fan and conveyor control. In consumer electronics, it can be used for energy harvesting, LED lighting and even electric vehicles.

Working Principle

EL7154CN is composed of two components: an input circuit and an output circuit. The input circuit is composed of six distinct inputs – an enable input, an over-draw input, and four control inputs. The output circuit consists of three gate drivers with independent gate outputs and a single drain output. The enable and over-draw inputs control the operation of the gate drivers, while the control inputs select the active channels.

The enable input lets the user decide if the gate drivers are enabled or disabled. The over-draw input lets the user decide the state of the outputs when the over-draw condition occurs. When the over-draw input is enabled, the drain output is pulled low. The four control inputs decide which channels to activate and deactivate. When enabled, each channel will activate the associated gate output and activate the drain output.

The operation of the EL7154CN-based gate drivers is fairly simple and can be operated manually or programmed with a microcontroller. The maximum operating frequency is 250kHz and the output voltage is adjustable from 0V to 20V. The peak output current is up to 3A.

The EL7154CN is suitable for use in high-speed, power MOSFET or IGBT applications requiring low-side switching. It allows for multiple output channels to be controlled from a single supply, and it is therefore capable of controlling multiple power outputs from a single device. Its high switching speed, low thermal impact, and low power consumption also make it a good choice for applications where power supply space is limited.
