DESCRIPTION

The TPS3613-01 supervisory circuit monitors and controls

processor activity by providing backup-battery switchover

for data retention of CMOS RAM.

During power-on, reset (RESET and RESET) is asserted

when the supply voltage (VDD or VBAT) becomes higher

than 1.1 V.

Thereafter, the supply voltage supervisor monitors VDD at

the SENSE pin through external feedback resistors and

keeps reset active as long as SENSE remains below the

threshold voltage, VIT.

An internal timer delays the release of the reset state to

ensure proper system reset. The delay time starts after

SENSE rises above the threshold voltage, VIT.

When SENSE drops below VIT, reset becomes active

again.

The TPS3613-01 is available in a 10-pin MSOP package

and is characterized for operation over a temperature

range of −40°C to +85°C.

描述

TPS3613-01监控电路监控

通过提供备用电池切换的处理器活动

用于CMOS RAM的数据保留。

在开机时，重启(复位和复位)被断言

当电源电压(VDD或VBAT)变高时

比1.1 V。

此后，电源电压监控器监视VDD

感觉针通过外部反馈电阻和

保持重置活动，只要感觉保持低于

阈值电压,维特。

内部计时器将重置状态的释放延迟到

确保系统正确复位。延迟时间在之后开始

感知高于阈值电压VIT。

当感觉低于VIT时，复位变为活动

一次。
