TC1271ARBVCTTR

电压监控器与手动复位输入 Voltage Supervisor with Manual Reset Input

General Description

For many of today’s microcontroller applications, care must be taken to prevent low-power conditions that can

cause many different system problems. The most common causes are brown-out conditions, where the system supply drops below the operating level momentarily. The second most common cause is when a slowly decaying power supply causes the microcontroller to begin executing instructions without sufficient voltage to sustain volatile memory RAM, thus producing indeterminate results.
