Charging management chip

Abstract

The invention discloses a charging management chip, which includes a charging control output module, a discharging control module, a battery voltage sampling input module, a fan driving output module, a buzzer output module, a dual-color LED control output module, a serial data output module. The control function of peripheral pins of the chip is programmable without being supported by peripheral controller, so that full automatization of the charging process detecting control can be realized. The invention needs lesser peripheral elements, and is easy for application design.

Description

technical field [0001] The invention relates to a charger, in particular to a charging management chip. Background technique [0002] At present, there are mainly two types of fast charging management chips, one is a single-chip microcomputer, and the other is a special chip for fast charging management. When using a single-chip microcomputer to realize a mid-to-high-end fast charger, the requirements for the single-chip microcomputer are relatively high. For example, more I / O ports need to be equipped with AD, etc., and related software needs to be developed, which often costs a lot. At present, the Ni-MH / Ni-Cd fast chargers have obvious market advantages, mainly Japanese brand chargers, including SANYO, SONY, PANASONIC, etc., as well as the joint venture brand GP Speedmaster, and the solutions they adopt are mainly with AD. MCU, and then write the program, followed by a dedicated ASCI chip to achieve. Many imported or domestic well-known brands of fast smart chargers use...

AI Technical Summary

Problems solved by technology

Many imported or domestic well-known brands of fast smart chargers use MCUs with AD functions, and need to write programs to realize all charging functions, which also brings software thresholds, thus limiting the number of manufacturers in the industry
