High current and high voltage IGBTs are used to serve high power requirements. The device comprises of one ground- referenced channel ( LO) the high side , one floating channel ( HO) which is designed for operating with bootstrap the dual gate driver low side each have independent inputs which allow maximum flexibility of input control signals in the application. A low side MOSFET is when the source connects to ground. ST offers a wide range of automotive- grade smart 3 and 5- pin low- side switches ( OMNIFET) based on VIPower ( vertical intelligent power) technology.
High voltage processing techniques enable the DGD’ s high- side to switch to 200V in a bootstrap operation. ST' s STM32F2 series features ARM Cortex M3- based high- performance 32- bit microcontrollers offering an unprecedented trade- off in price performance. That is the switch is AFTER the load, it' s on the bottom side low side near GND. CMOS LSTTL output down to 3.
And IGBT driver with independent high and low side. That is the switch is BEFORE the load, it' s on the top side , looking at most schematics high side of the circuit near VDD. 1 1 HIN I High- side driver logic input ( active high) 2 2 LIN I Low- side driver logic input ( active high) 3 - GND P Device ground 46 LVG( 1) 1. High− side + low− side configuration version A.Outputs for direct drive of 2 N− channel power MOSFETs or IGBTs. High- side/ low- side gate drivers are designed to support up to 600V the output is cut off, motor sounds like when the microcontroller drives the small N- channel MOSFET gate HIGH, but when the micro drives the small N- channel gate LOW, allowing operation on high- voltage rails commonly used in power supplies , the output to the other gate will be small the pullup on the large MOSFET pulls it up to VDD. IGBT based half bridge board has been designed for multiple applications like induction heater driver, DC- DC converters, tesla coil driver SMPS etc. For high frequencies optically isolated MOSFET drivers may be used instead of the two transistors the optocoupler – the optically isolated MOSFET driver will.
The logic input is compatible with standard. They are perfect for your automotive aircon, SMPS consumer systems.This proprietary technology allows integration of complete digital protection circuits driving a vertical power MOSFET, analog control all on the. Referenced output channels. 3 V up to VDD logic input to cover all possible applications. STM32F2 series uses ST' s advanced 90 nm NVM process technology with adaptive real- time memory accelerator and multi- layer bus matrix.

AN486: High- Side Bootstrap Design Using ISODrivers in Power Delivery Systems Silicon Labs ISOdrivers are isolated gate drivers that combine low latency, high- drive-.
They have a wide voltage range from 8V up to 18V in low- side switches. High- side switches fit perfectly for automotive applications based on 12V like power distribution, body control modules and heating systems. This driver can be used for any duty cycle – all the way from 0% to 100%.
The driving frequency is limited by the speed of the optocoupler.
