Nanopower uP Supervisory Circuits with Manual Reset and Watchdog Timer

General Description The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860–MAX6869 ultra-low-current (170nA, typ) microprocessor (µP) supervisory circuits combine voltage monitoring, watchdog timer, and manual reset input functions in a 5- pin SOT23 package. These devices assert a reset signal whenever the

纳安级功耗的微处理器监控电路，带有手动复位及看门狗定时器

MAX6854/MAX6855/MAX6856/MAX6858/MAX6860–MAX6869超低电流(典型值170nA)微处理器(µP)监控电路在5引脚SOT23封装内集成了电压监测、看门狗定时器和手动复位等功能。一旦监视电压低于工厂设定的复位门限，手动复位被触发或者看门狗定时器超时，该器件就会发出复位信号。在VCC升至复位门限以上或手动复位释放后，复位输出继续保持一个最短延时。工厂校准的复位门限以100mV的间隔从+1.575V至+4.625V (参见完整数据资料中的Threshold Suffix Guide)。每款器件提供6种最小复位延时选择，范围从10ms至1200ms。\nMAX6 ·超低工作电流170nA (典型值)\n·复位门限从+1.575V至+4.625V，间隔约为100mV\n·6种最短复位延时选择，从10ms到1200ms\n·手动复位可选功能\n·看门狗定时器可选功能\n·引脚可选的10ms/150ms (最小)复位延时(MAX6861/MAX6862/MAX6863)\n·对VCC上的短时瞬变不敏感\n·保证复位有效至VCC = +1.1V\n·三种复位输出选择\n·推挽/RESET\n·推挽RESET\n·漏极开路/RESET\n·无需外部元件\n·小巧的5引脚SOT23封装\n·引脚与TPS3836/TPS3837/TPS3838兼容(MAX6861/;

Three-phase motor driver for CD-ROMs

The BA6858A and BA6859A series are ICs developed for CD-ROM spindle motor drives. In addition to the functions of the BA6849 series, (short brake, reverse-rotation prevention circuit, rotation direction dector, and FG output), the BA6858A and BA6859A series have a built-in brake mode switching pin
