文档解析

MAX6733系列双电压监控电路设计用于监控两个电源电压，提供推挽式复位输出，简化电路设计。它支持工厂预设的双阈值电压（VCC1范围+1.575V至+4.63V，VCC2范围+0.79V至+3.08V），任一电压低于阈值时触发复位。电路集成看门狗定时器，但无手动复位输入，复位超时周期可选六种（最小1.1ms到最大1120ms）。技术细节包括看门狗独立输出，启动延迟最小35秒，正常模式超时最小1.12秒，支持高低电平切换检测。复位输出为推挽结构，输出电压在未断言时达0.8×VCC1。电气参数涵盖电源电压+0.8V至+5.5V，典型电流14μA，复位延迟22μs（针对RSTIN）。封装为SOT23-6，温度范围-40°C至+85°C。应用场景包括打印机、传真机和机顶盒，优势在于高集成度、低功耗（典型14μA）和紧凑封装，适用于空间受限的多电压电子系统。

Single-/Dual-/Triple-Voltage µP Supervisory

Circuits with Independent Watchdog Output

General Description

The MAX6730–MAX6735 single-/dual-/triple-voltage

microprocessor (µP) supervisors feature a watchdog

timer and manual reset capability. The MAX6730–

MAX6735 offer factory-set reset thresholds for monitor-

ing voltages from +0.9V to +5V and an adjustable reset

input for monitoring voltages down to +0.63V. The com-

bination of these features significantly improves system

reliability and accuracy when compared to separate

ICs or discrete components.

The active-low reset output asserts and remains asserted

for the reset timeout period after all the monitored volt-

ages exceed their respective thresholds. Multiple factory-

set reset threshold combinations reduce the number of

external components required. The MAX6730/MAX6731

monitor a single fixed voltage, the MAX6732/MAX6733

monitor two fixed voltages, and the MAX6734/MAX6735

monitor two fixed voltages and one adjustable voltage. All

devices are offered with six minimum reset timeout peri-

ods ranging from 1.1ms to 1120ms.

The MAX6730–MAX6735 feature a watchdog timer with

an independent watchdog output. The watchdog timer

prevents system lockup during code execution errors.

A watchdog startup delay of 54s after reset asserts

allows system initialization during power-up. The watch-

dog operates in normal mode with a 1.68s delay after

initialization. The MAX6730/MAX6732/MAX6734 provide

an active-low, open-drain watchdog output. The

MAX6731/MAX6733/MAX6735 provide an active-low,

push-pull watchdog output.

Other features include a manual reset input (MAX6730/

MAX6731/MAX6734/MAX6735) and push-pull reset out-

put (MAX6731/MAX6733/MAX6735) or open-drain reset

output (MAX6730/MAX6732/MAX6734). The MAX6730–

MAX6733 are offered in a tiny SOT23-6 package. The

MAX6734/MAX6735 are offered in a space-saving

SOT23-8 package. All devices are fully specified over

the extended temperature range (-40°C to +85°C).

*Note:

Insert the threshold level suffixes for V

1 and V

(Table 1) after “UT” or “KA.” For the MAX6730/MAX6731, insert

only the V

1 threshold suffix after the “UT.” Insert the reset

timeout delay (Table 2) after “D” to complete the part number.

For example, the MAX6732UTLTD3-T provides a V

1 threshold

of +4.625V, a V

2 threshold of +3.075V, and a 210ms reset

timeout period. Sample stock is generally held on standard ver-

sions only (see the Standard Versions table). Standard versions

have an order increment requirement of 2500 pieces.

Nonstandard versions have an order increment requirement of

10,000 pieces. Contact factory for availability.

Typical Operating Circuit and Pin Configurations appear at end of data sheet.
