适用于 RAM 保持模式的增强型产品电池备份监控器

The TPS3619 and TPS3620 families of supervisory circuits monitor and control processor activity by providing backup-battery switchover for data retention of CMOS RAM. During power on, RESET is asserted when the supply voltage (VDD or VBAT) becomes higher than 1.1 V. Thereafter, the supply voltage su • Supply Current of 40 µA (Max)\n• Precision Supply-Voltage Monitor 3.3 V, 5 V, and Other Options on Request\n• Power-On Reset Generator with Fixed 100-ms Reset Delay Time\n• Battery Freshness Seal (TPS3619)\n• 8-Pin Mini Small-Outline Package (MSOP) Package\n• Controlled Baseline\n• One Fabrication;
