带 HMI 的汽车 HVAC 控制参考设计
TIDA-020010
概述
This reference design offers a cost-effective solution for a heating, ventilation, and air conditioning (HVAC) human-machine interface (HMI) application. This reference design incorporates a synchronous step-down converter, multiple channel half-bridge motor driver for brushed DC motors (BDC), multiple channel light-emitting diode (LED) driver, which sets LED light intensity according to the ambient light intensity, that is measured by the ambient light sensor, The high-side switch on this reference design drives various loads, multiple hall-sensors are used for contactless measurement of the rotary knobs, tracking voltage regulator supplies off board sensors and multiplexer is used to multiplex multiple analog sensor outputs to the microcontrollers analog to digital converter (ADC).
特性
- Withstands reverse battery protection
- Drives up to 6 BDC motors
- Automatic LED dimming based on ambient light intensity
- Contactless rotation detection for the rotary knobs
- Fully protected high-side power switch with accurate current sense
我们开发的全面组装电路板仅用于测试和性能验证，不可用于销售。
