概述

完整的数据资料 (PDF, 128kB) 英文 下载 The DS1810 EconoReset uses a precision temperature reference and comparator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces reset to the active state. When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 150ms to allow the power supply and processor to stabilize.

关键特性

Automatically restarts a microprocessor after power failure Maintains reset for 150ms after VCC returns to an in-tolerance condition Reduces need for discrete components Precision temperature-compensated voltage reference and voltage sensor Low-cost TO-92 or space saving surface mount SOT-23 packages available Push-Pull output for low current operation Operating temperature -40°C to +85°C
