文档解析

MAX6730系列单电压监控电路是一款专为监控单一电源电压设计的微处理器监控芯片。它集成了看门狗定时器和手动复位功能，通过工厂预设的复位阈值电压（范围从+1.575V到+4.63V）确保系统在电压异常时可靠复位。该电路提供开漏复位输出，需要外部上拉电阻，并支持六种可选的复位超时周期（从1.1ms到1120ms），以提高系统稳定性和抗干扰能力。技术规格包括独立的看门狗输出，启动延迟最小35秒，正常模式超时最小1.12秒，可防止代码执行错误导致的系统锁死。手动复位输入配备内部50kΩ上拉电阻，简化外部电路设计。电气特性涵盖工作电压范围+0.8V至+5.5V，典型电流消耗14μA，复位阈值温度系数20ppm/°C，保证复位有效至VCC=+0.8V。封装采用SOT23-6，工作温度范围-40°C至+85°C。该电路适用于多电压系统、电信设备、便携设备和工业控制等场景，特点包括低功耗设计、免疫短电压瞬态干扰，以及小尺寸封装，便于集成到空间受限的应用中。

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.
