AAT4682_06 数据手册
Dual Electronic Resettable Switch General Description The AAT4682 dual electronic resettable fuse is a member of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family. It has two 1A current limited P-channel MOSFET power devices that remain fully enhanced as long as the input power supply is above an under-voltage lockout threshold and the load is below the current limit setting. If the load increases above the current limit setting, as is the case during a short circuit, the MOSFET effectively becomes a constant current source equal to the current limit. If the current limit condition persists long enough to heat the MOSFET to an extreme temperature, both devices will thermal cycle off and on until the current limit condition is removed. Independent open drain FAULT flags signal an over-current or over-temperature condition. Quiescent current typically is a low 10µA. The AAT4682 is available in a Pb-free, 6-pin SOT23 package and is specified over the -40°C to +85°C temperature range.

物料型号: - AAT4682IGU-T1

器件简介: - AAT4682是一款双通道电子可重置保险丝,属于AnalogicTech的特定应用功率MOSFET(ASPM)产品系列。它包含两个1A电流限制的P沟道MOSFET功率设备,只要输入电源高于欠压锁定阈值且负载低于电流限制设置,就会保持完全增强状态。

引脚分配: - Pin 1 (FAULTA):通道A开漏输出,表示过电流和过热状况。 - Pin 2 (GND):接地连接。 - Pin 3 (FAULTB):通道B开漏输出,表示过电流和过热状况。 - Pin 4 (OUTB):通道B P沟道MOSFET漏极。 - Pin 5 (IN):通道A和通道B P沟道MOSFET源极。 - Pin 6 (OUTA):通道A P沟道MOSFET漏极。

参数特性: - 双P沟道MOSFET,500mA稳态负载电流,600mA最小电流限制触发点,低静态电流,典型值为10µA,过温保护,快速瞬态响应:<1µs响应到短路,400mΩ典型RDS(ON),欠压锁定,温度范围:-40°C至+85°C,带2ms消隐的FAULT标志,6引脚SOT23封装。

功能详解: - AAT4682通过电流限制到预设水平来保护免受过载短路条件的影响。专利的快速响应电流限制回路可以在微秒级限制负载电流,并在短路条件移除后立即重置到低阻抗状态。过电流状况由开漏FAULT输出在两毫秒消隐间隔后报告。

应用信息: - AAT4682适用于保护诸如USB、RS232和并行端口等外围端口。输入电容器保护电源免受过载瞬态电流的影响。每个输出需要大约1µF的小输出电容以确保在电流限制激活时的稳定性。对于连接到AAT4682的电容性负载,将以不超过电流限制设置的速率充电。
