SX8122ISTRT 模拟定时器说明1V Motor/LED timerDescription FeaturesThe SX8122 is an analog controlled of 1 Volt motor/LED timer. The SX8122 toggles its output high or low according to the state of an analog pin (TRIGGER). Threshold voltages on the analog pin are set to 1/3 and 2/3 of VDD. One output pin (LED) send bursts when the motor is on to control a LED which threshold voltage is above VDD or to generate a boosted supply. One output goes low when VDD is higher than the full charge voltage of an NiMH cell to control a minimal charger. The SX8122 controls its IO state starting at 0.6V to facilitate power-up 低于 1V的模拟定时器平台，针对采用电池工作的低电压小型应用，彻底变革了传统的555定时器。新型SX8122模拟定时器通过其内在的0.9V工作电压，提供同类最佳的电池寿命，而无需外部升压转换器和电感，节省了电路板空间和成本。它还为传统555定时器增加了低压特性，一个输出控制用于控制DC电机或其它连续低电压的元件，另一个输出产生脉冲链，可用单只电池驱动一只高亮度LED。这种特性组合使SX8122非常适合于广泛的小型消费家电与办公电器，如电动牙刷、蜂鸣器、玩具和LED激光笔等。该器件亦带有一个电压监控器，使NiMH或NiCd供电设备可以实现简单的USB充电器。  SX8122ISTRT 模拟定时器现货订购热线： SX8122ISTRT 模拟定时器 pdf datasheet(责任编辑：www.gongwin.com) |
