Under Voltage and Over Voltage monitoring

  The TPS3702 family of devices combines two comparators and a precision reference for overvoltage and undervoltage detection. The TPS3702 features a wide supply voltage range (2 V to 18 V) and highly accurate window threshold voltages (0.9% over temperature). The TPS3702 is designed for systems that require an active low signal if the voltage from the monitored power supply exits the accuracy band. The outputs can be pulled up to 18 V and can sink up to 10 mA. Unlike many other window comparators, the TPS3702 includes the resistors used to… Read More

Motion Sensing & LED Control

Reference Design Description The Motion Sensing & LED Control Reference Design demonstrates how to use Zilog’s Z8FS040 ZMOTION MCU with the IXYS LDS8710 High-Efficiency LED Driver and explains how to implement features such as ambient light detection and LED dimming in addition to passive infrared motion detection. It also illustrates how the combined capabilities of both products are an exceptional choice for energy management functions in applications ranging from low-power displays and backlighting to ambient room lighting control. Features Integrated passive infrared (PIR) motion sensing and LED control combined in a single… Read More
