PMIC (Power Management Integrated Circuit) is a microelectronic device that can convert an electrical energy source from one voltage to another, allowing designers to optimize the power needed for a system’s natural working conditions. Different PMICs are designed to manage specific operating environments. Among them, Gate Drivers are one type. They assist in connecting power circuitry by providing the necessary voltage and current to energize semiconductors such as transistors and thyristors. In this article, we will take a closer look at the LT1336IN#PBF Gate Driver and its application fields and working principle.

The LT1336IN#PBF is a high-voltage MOSFET high-side driver integrated with a synchronous step-up converter, designed to enable operation at up to 400 V in hot swap circuits. The device is available in an 8-pin SOIC package with a footprint of 3.9mm x 4.9mm. The device has an operational temperature range of -55°C to +125°C and can withstand a surge voltage of 1500V. The LT1336IN#PBF takes in a PWM control voltage from +2.2V to +7V, and is capable of driving a wide range of MOSFETs and other power switching devices.

The LT1336IN#PBF Gate Driver has various applications. Power over Ethernet power switches, or PoE, are becoming increasingly common, as are industrial and automotive power supply systems such as DC-DC converters. Thanks to its high-voltage and high-current rating, the LT1336IN#PBF is ideal for designs requiring high voltage, high power ratings, combined with a small footprint. It is also commonly used in motor and heater control systems, creating an efficient control loop that is capable of rapidly modulating power into the load.

Now let\'s take a look at the working principle of the LT1336IN#PBF. The switching circuit of the device is based on the buck-boost topology and consists of an inductor, a diode, and a pair of MOSFETs. When the internal high-side MOSFET is turned on and the external low-side MOSFET is turned off, the inductor current will build up and charge the output capacitor. Then the internal low-side MOSFET is turned on, and the external high-side MOSFET is turned off. This will cause the output capacitor to be discharged, and the inductor current will flow through the inductor, the diode, and the MOSFETs in reverse order. This is the on-off cycle of the switching circuit, which is repeated to create a stable output voltage.

The LT1336IN#PBF Gate Drive also features an over-temperature protection circuit and a voltage protection circuit. These two circuits ensure that the output voltage will not exceed the device’s operating range, or damage the device if the junction temperature exceeds the safe limit. Thanks to its integrated protection, the LT1336IN#PBF provides reliable and efficient operation, making it ideal for a wide range of hot swap applications.

In conclusion, we have discussed the LT1336IN#PBF Power Gate Driver, its application fields, and its working principle. The LT1336IN#PBF is a high-voltage, high-current MOSFET driver, designed for use in high-power PoE designs, DC-DC converters, motor control systems, and more. The device features an advanced switching circuit, with an over-temperature protection circuit and voltage protection circuit to ensure safe and reliable operation. All in all, the LT1336IN#PBF is a great choice for applications that require a reliable and efficient power gate driver.
