CHT-HADES2P is a high-temperature, high-reliability single-chip primary side of a gate driver solution. It implements a current mode controlled DC-DC flyback converter for the generation of the on-board power supplies and the isolated data transmission from the external control interface to the 2 secondary sides and performs local fault management. This device has been designed in a way to reduce as much as possible the required number of external passive devices and to limit the requirement in high capacitor values (large footprint at high temperature). It features a UVLO monitoring on the incoming power supply, a linear voltage regulator to generate the local 5V supply voltage, and an on/off keying modulation of the data signal towards the secondary side. It offers a wide voltage range for the input PWM signals (5 to 15V) and hysteresis to enhance immunity to system noise; it also features a spike filtering function on those PWM signals to prevent spurious turn-on/turn-off of the secondary gate drivers.
