The bidirectional transformer interface transmits the primary side input commands, secondary side output faults, and power supply faults. Asynchronous data transmission is through high frequency narrow pulses to avoid duty cycle restrictions, to achieve shorter delays, and to prevent any transformer core saturation issues. The IX6610 contains all the necessary blocks to implement a power converter that supplies isolated power to the secondary side IGBT drivers. IX6610 is a primary side device with built-in interlock and dead time control that can be interfaced directly to a low voltage microcontroller to provide input signal conditioning as well as fault management. The IX6610 operates over a temperature range of -40°C to +85°C. The IX6610 is available in either 28-lead TSSOP with exposed pad or as tested die.
