70V Smart Gate Driver with Servo (FOC) Controller in HW and Buck Converter

The TMC9660 is a highly integrated monolithic gate driver and motor controller IC with buck converter.

It includes a smart gate driver, a high-performance motion controller with hardware-based field-oriented control (FOC) and servo controller (velocity, position, ramp generator), motor position feedback interfaces (A/B/N encoder, hall), an analog signal processing block for bottom shunt current measurement (programmable current-sense amplifiers [CSAs] and analog-to-digital converters [ADCs]). It also includes a powerful and flexible power management unit (PMU) along with a buck converter and programmable low-dropout (LDO) regulators. For overall control and communication with an external processor through SPI or UART, a preprogrammed 32-bit microcontroller is embedded. The processor system supports either low-level direct register access to all motor control peripherals or higher-level parameter mode access for extended functionality and ease of use. For initial configuration of system hardware connections and software selection, a bootloader is available also supporting permanent storage of this configuration in the one-time-programmable (OTP) memory.
