CAT102集成电路（IC）的监控器规格书PDF中文资料

CAT102属于集成电路（IC）的监控器。由安森美半导体制造生产的CAT102监控器PMIC 监控器用于监视和/或控制电路中的电压轨，能够连接微控制器以维持一定的功率限值。监控器类型包括电池备用电路、监控器、多电压监控器、电源监控器、稳压器/监控器、复位计时器、定序器、简单复位/上电复位、智能开/关控制器、系统管理器、电压检测器和看门狗电路。

DESCRIPTION

The CAT102 is a low-voltage reference and amplifier. Designed for the control loop of low-voltage power supplies, the reference voltage has been designed for 600 mV. Over a temperature from -40°C to 85°C, the reference voltage is within 8 mV of the nominal 600mV. In addition, the error amplifier output and the supply voltage pin (IN) are on separate pins.

FEATURES

■ 600 mV low voltage reference
