The ICL7667CPAZ is part of a family of popular gate drivers used in power management integrated circuits (PMICs) and is a great addition to any board when you need to efficiently control its power. This particular gate driver is a unique device, providing control of up to four separate power control circuits in a single package. It also offers high current drive capabilities and low power consumption.

The ICL7667CPAZ is a monolithic integrated circuit that incorporates two high-side, N-channel MOSFETs and two low-side, N-channel MOSFETs. These devices can be connected in any combination to multiple gate drives, up to four, so that multiple power circuits can be simultaneously controlled. The ICL7667CPAZ features built-in circuitry designed to protect the MOSFETs against damages caused by overvoltage, overtemperature, and short-circuiting.

The ICL7667CPAZ is engineered to drive higher current levels than other gate drivers, up to 100 mA and with voltages ranging from -0.3 to 20 V. It also offers exceptional power efficiency and can operate at temperatures up to 85°C with a low supply current of only 2.5 mA. This helps lower overall power dissipation thanks to its low quiescent current characteristics.

The ICL7667CPAZ can be used for many purposes including motor control, power management, and high-voltage switching. It has many applications fields such as automotive, consumer, industrial, and medical electronics. It also has high transient immunity, very low-jitter, and good ease of use, making it popular for switching applications that require ultimate control and precision.

When it comes to how it works, the ICL7667CPAZ is designed to drive several high side, low side, and high voltage gate drivers and switches. It will identify which MOSFET is active or open and if shorted, will automatically shutoff the voltage supply to avoid damage. Its internal circuit also provides positive or negative voltage control as well as adjustable frequency and gain settings.

In conclusion, the ICL7667CPAZ is an advanced type of gate driver that can be used in various power management integrated circuits and provides high current drive capabilities and low power consumption. It has various applications fields such as automotive, consumer, industrial, and medical electronics and is suitable for motor control and high-voltage switching applications. It also offers high transient immunity, very low-jitter, and good ease of use.
