描述 Description

A monitoring and protection circuit for 3-cell 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 16KB self-programming flash program memory, 1KB SRAM, 512-bytes 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 0.84μV. It also supports up to 8 MIPS throughput at 8MHz,? 4-25V operation.

特性 Features

·Over-current protection (charge and discharge)
·Short-circuit protection (discharge)
·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

簡介

ATmega16HVB屬于集成電路（IC）的微控制器。由制造生產(chǎn)的ATmega16HVB微控制器微控制器產(chǎn)品是相對復雜的用戶可編程數(shù)字邏輯器件。這些產(chǎn)品與視為微控制器的器件密切相關，兩者之間的區(qū)別主要體現(xiàn)在制造商選擇的用詞。不過按照傳統(tǒng)，微控制器集成了工作存儲器，也更可能包含混合信號外設，并且往往與更簡單的軟件范例結合使用，旨在重復執(zhí)行一系列預定義的任務。
