MAX706ESA产品概述

MAX705-MAX708 / MAX813L微处理器(μP)监控电路降低组件的复杂性

和数量需要监控μP系统供电和电池的功能。

这些设备显著改善系统的可靠性和准确性比单独的ICs或离散的组件。

The MAX705–MAX708/MAX813L microprocessor (μP)

supervisory circuits reduce the complexity and number of

components required to monitor power-supply and battery

functions in μP systems. These devices significantly improve

system reliability and accuracy compared to separate ICs or

discrete components

MAX705 / MAX706 / MAX813L提供四个功能:

1.复位输出在升高,省电,警戒灯火管制条件。

2.一个独立的监督机构输出低,如果监管机构输入并且没有在1.6秒内。

3.1.25 v阈值检测器电源失效预警,监测检测电池电量过低,或者除了+ 5 v电源。

4.一个手工输入校验。

1.A reset output during power-up, power-down, and brownout conditions.

2.An independent watchdog output that goes low if the watchdog

 input has not been toggled within 1.6 seconds.

3.A 1.25V threshold detector for power-fail warning, low-battery detection,

 or for monitoring a power supply other than +5V.

4.An active-low manual-reset input.

MAX707 / MAX708 MAX705 / MAX706是一样的,除了一个高电平复位看门狗定时器被替换。

MAX813L MAX705一样,除了提供复位而不是重置校验。

两个电源电压监控水平可用:MAX705 / MAX707 MAX813L产生一个复位脉冲电源电压低于4.65 v时,

而MAX706 / MAX708产生一个复位脉冲低于4.40 v。

所有四个部分都有下降,所以μMAX®包。

The MAX707/MAX708 are the same as the MAX705/MAX706,

except an active-high reset is substituted for the watchdog timer.

The MAX813L is the same as the MAX705, except RESET is provided instead of active-low RESET.

Two supply-voltage monitor levels are available:

The MAX705/MAX707/MAX813L generate a reset pulse when the supply voltage drops below 4.65V,

while the MAX706/MAX708 generate a reset pulse below 4.40V.

All four parts are available in 8-pin DIP, SO and μMAX® packages.
