March 2005 rev 1.3 ASM1233D-L/D/M Low Power, 5V/3.3V, µP Reset, Active LOW, Open-Drain Output Applications • • • • • • • Set-top boxes Cellular phones PDAs Energy management systems Embedded control systems Printers Single board computers General Description The ASM1233D-L/1233D/1233M are voltage supervisors with low-power, 5/3.3V µP Reset, with an active LOW, open-drain output. Maximum supply current over temperature is 15µA for 3.3V devices and 20µA for 5V devices. The ASM1233D-L/1233D/1233M generates an active LOW reset signal whenever the monitored supply is out of tolerance. A precision reference and comparator circuit monitors power supply (VCC) level. The tolerance are 5%,10% and 15%. When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces an active LOW reset signal. After VCC returns to an in-tolerance condition, the reset signal remains active for 350ms to allow the power supply and system microprocessor to stabilize. The ASM1233D-L/1233D/1233M is designed with an opendrain output stage and operates over the extended industrial temperature range. These devices are available in compact SOT-223, SO-8 and TO-92 packages. Other low power products in this family include ASM1810/11/ 12/15/16/17.

1. 物料型号: - ASM1233D-L/D/M

2. 器件简介: - ASM1233D-L/1233D/1233M是低功耗、5V/3.3V微处理器复位电压监控器,具有主动低电平、开漏输出。这些器件在供电电压超出容差时生成主动低电平复位信号。它们设计用于在扩展的工业温度范围内工作,并以SOT-223、SO-8和TO-92封装提供。

3. 引脚分配: - TO-92封装:1脚为GND(地),2脚为RESET(主动低电平复位输出),3脚为VCC(电源输入)。 - SO-8封装:1脚为RESET,2脚为VCC,3、5、6、7和8脚为NC(无连接)。 - SOT-223封装:与TO-92封装相同。

4. 参数特性: - 供电电压:1.2V至5.5V。 - 输出电压:RESET断言时0.4V。 - 输出电流:当输出为0.4V时为8mA。 - 工作电流:小于等于3.6V时为6至15μA。 - 复位电压阈值:ASM1233D-LZ系列为2.98V至3.15V,ASM1233DZ系列为4.5V至4.74V,ASM1233M系列为4.25V至4.75V。

5. 功能详解: - 这些器件在供电电压超出预设容差时生成内部掉电信号,触发主动低电平复位信号。在供电电压恢复到容差范围内后,复位信号保持活动350ms,以便电源和系统微处理器稳定。

6. 应用信息: - 应用于机顶盒、手机、PDA、能源管理系统、嵌入式控制系统、打印机和单板计算机等。

7. 封装信息: - 提供SOT-223、SO-8和TO-92封装,具体尺寸和参数在文档中有详细描述。
