描述 Description

A monitoring and protection circuit for 3- and 4-cell Li-ion applications that require the highest safety, including safe authentication, low cost, and high utilization of the cell energy. The microcontroller includes 32 KB self-programming Flash program memory, 2 KB SRAM, 1024B EEPROM, 2, 3 or 4 cells in series, over-current, high-current, and short-circuit protection, 12-bit voltage A/D converter, 18-bit coulomb counter-current A/D converter, and debugWire interface for on-chip debug.The device features autonomous battery protection during charging and discharging and supports very accurate accumulated current measurements using an 18-bit A/D converter with a resolution of 0.84 µV. It also supports up to eight MIPS throughput at 8 MHz, 4-25V operation.

特性 Features

·High-voltage outputs to drive N-channel charge/discharge FETs
·Optional deep under voltage recovery mode - allowing 0-volt charging without external precharge FET
·Optional high-voltage open drain output - allowing 0-volt charging with external precharge FET
·Integrated cell balancing FET

简介

ATmega32HVB属于集成电路（IC）的微控制器。由Microchip制造生产的ATmega32HVB微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。
