NSUC1610 is an integrated drive and 4-way half-bridge microcontroller, mainly used to control low-power DC motor, can support the drive of DC brush motor, DC brushless motor, stepper motor, etc., widely used in new energy vehicles. The chip adopts advanced high temperature and high pressure process, the maximum temperature can be supported to 175°C, the maximum voltage withstand to 40V, and has overvoltage protection function, LIN port can support -40V~40V voltage, BVDD pin can support -0.3~40V voltage. The chip uses the ARM Cortex-M3 core, which uses separate data buses and address buses to improve the efficiency of fetching instructions and data.
Product Features
• Cortex M3 processor, the compiler environment uses Keil standard compiler and development tools, common programmer resources, easy development and debugging
• Car battery 12V direct power supply, chip power supply can withstand 40V short-term overvoltage
• Integrated power level MOSFETs (4 half-bridges), drive current up to 1A (500mOhm Rdson), integrated the corresponding gate drive and upper tube drive required charge pump power supply
• Integrated configurable DAC to configure comparator thresholds for overcurrent protection and microstep control of stepper motors
• Supports the 4-wire LIN bus, and the LIN interface meets the requirements of ±40V over-voltage resistance. In addition, there is a GPIO that can support high voltage (12V), which is convenient for customers to use high voltage PWMIO directly to do motor control
• Dual temperature sensor: one on the power side for overtemperature shutdown, and the other on the low-voltage side for chip temperature detection
• Wafer junction temperature up to 175°C meets the vehicle Grade 0 application target
Application
• Automotive electronic actuators
• Electronic air outlet
• Electronic water valve
• AGS controller
• Electronic charging door control
