PMIC - Gate Drivers are used to drive high current power devices in a wide range of electrical and electronic systems. The latest development in this field is the FAN3225TMX, which is a high efficiency single-channel, dual-gate static driver.

The FAN3225TMX is designed to drive high-side N-channel power MOSFETs and MOSFET drivers in applications requiring up to 20-ampere of continuous current. The device’s dual-gate architecture enables drives of both low side and high side switches in one IC and features a low quiescent supply current to reduce system power consumption.

The FAN3225TMX integrates a high-side gate driver with built-in level shifter, current limit, over temperature and under voltage protection circuits. It also includes built-in compensated bootstrap diodes and an adjustable slow-start circuit that avoids any overshoot. The device also offers a number of other benefits and features, including programmable slew rate, fast turn-off time, excellent current limit accuracy and adjustable OVP threshold.

The FAN3225TMX is capable of driving high-current loads up to 20A peak and can operate at a switch frequency of up to 100kHz, making it ideal for driving large and high-speed MOSFETs. Its integrated level shifter enables direct driving of two N-channel MOSFETs from a single supply voltage of up to 55V, while its adjustable slow-start circuit provides protection against pulses and overshoot.

The main features of the FAN3225TMX are:

• High-side cross-conduction suppressor that eliminates cross conduction issues
• Built-in level shifter for direct driving of 2 N-channel MOSFETs from one single supply
• Integrated current limit, over-temperature and under-voltage protection circuits
• Compensated bootstrap diodes for improved surge current handling
• Adjustable slow-start circuit for protection against pulses and overshoot

The FAN3225TMX is a valuable addition to the range of PMIC - Gate Drivers and is well suited to a range of applications, such as motor drive systems, telecom infrastructure, automatic lamps, industrial drives, solar power systems and battery management.

In terms of its working principle, the FAN3225TMX is designed to drive two high-side N-channel MOSFETs independently, one at a time. Its logic control pins enable the device to be used in low power control applications, while its integrated level shifter allows it to be used with single supplies up to 55V. This device also features a high current limit and adjustable fast rise time and slow decay time to meet the needs of different applications. The device also protects against over-temperature, under-voltage, and cross-conduction events.

The FAN3225TMX is a simple and reliable solution for driving large and high-speed MOSFETs, providing a number of benefits for a range of applications, including motor drives, automatic lamps, solar cells, and telecom infrastructure.
