TC4468CPD Application Field and Working Principle

TC4468CPD is an automotive-grade power management integrated circuit (PMIC) with a low on-resistance, high-voltage, low saturation, and high-side/low-side gate drive capability. It is designed with a power MOSFET in a high-side/low-side configuration and has a wide range of applications in automotive electronics, including those requiring high-side/low-side drive capabilities. TC4468CPD can also be used in high-voltage industrial and consumer applications.

The TC4468CPD gate driver combines a fast high-side gate driver (ITFET) and a fast low-side gate driver (OSFET) for low-side gate drive capability. This allows the device to switch large loads without the need for external power MOSFETs or gate driver circuits. The device also features a high-side gate drive current of up to 4A and a low-side gate drive current of up to 2A.

The device is designed to minimize power dissipation during high-side or low-side operation. The device takes advantage of its fast switching capability to minimize both rise and fall times, resulting in low power consumption and high efficiency. The device also includes built-in over-current protection, which prevents power MOSFETs from being damaged due to over-current conditions.

The device also includes a high frequency current mode logic (CML) driver, enabling it to be used in high frequency, high-side/low-side applications. The device includes a low power standby mode, which reduces power consumption while in standby. Additionally, the device includes a programmable slew rate that can be used to minimize EMI and optimize the power MOSFET switching time.

The device is designed to operate with input voltages from 2.7V to 20V and can handle load currents up to 4A, making it suitable for a wide range of automotive applications. The device also has a very low quiescent current of less than 1 uA and a maximum junction temperature of 125°C.

In summary, the TC4468CPD is an automotive-grade PMIC with a low on-resistance and high-voltage gate drive capability, designed with a power MOSFET in a high-side/low-side configuration. It has a high frequency current mode logic driver, a low power standby mode, and a programmable slew rate, making it ideal for use in high-frequency, high-side/low-side applications. It is suitable for use in automotive, industrial, and consumer applications, with input voltages of up to 20V and a maximum junction temperature of 125°C.
