Description
The ST72F321 and ST72321 devices are members of the ST7 microcontroller family designed for mid-range applications.
All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set and are available with FLASH or ROM
program memory.
Under software control, all devices can be placed in WAIT, SLOW, ACTIVE-HALT or HALT mode, reducing power consumption when the application is in
idle or stand-by state.
The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of
highly efficient and compact application code. In addition to standard 8-bit data management, all ST7 microcontrollers feature

ACS710: 带宽 120 kHz,高压绝缘电流传感器 IC,具有集成过流检测功能 Allegro ACS710 电流传感器 IC 为工业、商业和通信系统中的电流传感应用提供经济实惠的精确解决方案。此设备配有小尺寸壁挂式包装,便于用户使用。 ACS710 设备有一个精确的线性霍尔传感器集成电路,且其铜制的电流路径靠近晶片的表面。外加电流流经铜制电流路径,而霍尔传感器 IC 的模拟输出电压则对外加电流产生的磁场进行线性跟踪。ACS710 的精确性由于这一专利包装设备实现了化,因为霍尔元件的位置与需要测量的电流十分接近。 Allegro 独有的集成屏幕技术提供的对电流导体 dV/dt 信号和杂散电场的高抗扰能力,确保高端、高电压应用中的低输出电压纹波和低偏置漂移。 过流电压输入(VOC 管脚)让用户能为此设备设定过流故障标准。当流经铜制电流路径 (介于 IP+ 和 IP– 管脚之间)的电流超过了这一标准,断开的漏极过流故障管脚会转为逻辑低状态。ACS710 内部线性霍尔传感器 IC 的写入只读程序使得模拟和数字输出信号都异常精准。 用于电流感应的典型铜制路径内电阻是 1 mΩ,功率耗损很小。而且,电流路径与低压传感器的输入和输出均为绝缘。这样,ACS710 传感器系列可用于那些要求电气...
A4941 A4941GLPTR-T A4941GLP-t Three-Phase Sensorless Fan Drive Features and Benefits Sensorless (no Hall sensors required) Soft switching for reduced audible noise Minimal external components PWM speed input FG speed output Low power standby mode Lock detection Optional overcurrent protection dzsc/18/4310/18431097.jpg Description The A4941 three-phase motor driver incorporates BEMF sensing to eliminate the requirement for Hall sensors in fan applications. A pulse wave modulated (PWM) input is provided to control motor speed, allowing system cost savings by eliminating external variable power supply. PWM input can also be used as an on/off switch to disable motor operation and place the IC into a low power standby mode. The A4941 is provided in a 16-pin TSSOP package (suffix LP) with an exposed thermal pad. It is lead (Pb) free, with 100% matte tin leadframe plating.
