L6388ED013TR Datasheet/PDFL6388ED013TR is a non-inverting MOSFET gate driver integrated circuit (IC) designed to work efficiently with high-side and low-side MOSFETs for synchronous buck converter applications and other similar ones. Delivering high accuracy, low RDSon, faster switching performances and added safety and protection, this driver IC is very reliable and practically unparalleled in the area of driver ICs.
The main application field of this IC are systems which implement SMPS (switched mode power supply) controllers, point-of-load converters, POL converters, multi-phase power management (e.g. computers, peripherals and communication systems) and DC-to-DC converters.
This device has two chipsets: one to set the voltage and one to control the power device to allow power control. This makes it an efficient and reliable driver IC for improved safety.
The first part of the device is the voltage regulator section, which offers on-chip voltage regulation. This allows the electrical current to be regulated and precisely adjusted, allowing for the programmed load regulation for synchronous buck converter applications, improved system stability and better response times.
The voltage regulator has two pins for negative and positive power supply and an output voltage pin. It offers fast response times, stable and reliable operation, high-side current limitation, programmable slew rate and soft start capabilities, reverse current limiting and over-temperature protection.
The second part is responsible for controlling the power device. It includes an advanced MOSFET driver, providing fast and accurate switching operations, low on-resistance, low power and solid performance. The driver also provides independent control of high-side and low-side MOSFETs, allowing for parallel switches and improving battery lifetime.
The driver includes fault detection with programmable trip points, high-impedance open loop output fault flag, over-temperature protection and an output clamping circuit. Moreover, the device can be used for automotive and consumer applications, making it very versatile.
In conclusion, the L6388ED013TR by STMicroelectronics is a non-inverting MOSFET gate driver IC designed to work efficiently with high-side and low-side MOSFETs for synchronous buck converter applications and other similar ones. With improved accuracy, low RDSon, faster switching performances and added safety and protection. This driver IC is very reliable and practically unparalleled in the area of driver ICs.
