双节锂电线性充电管理芯片ME4052A助力对讲机充电,充电电流可达1A,ESOP8封装解决散热问题
锂离子电池广泛应用于我们生活中的方方面面。医疗产品、智能手表、手机、对讲机、笔记本、电子玩具、美容仪、电动汽车等等。
单节锂电池的供电电压是3V-4.2V,而这样的功率已经无法满足日新月异的消费类电子产品了。双节锂电池的供电电压6-8.4V,在同样电流情况下,增加了功率,满足输出功率20W以上的应用。
在产品设计和芯片应用中,锂电池的电路,离不开以下三大基本电路来控制。
双节串联锂电池可以提供6V-8.4V的供电电压,微盟电子ME4052A双节锂电线性充电管理芯片性能稳定,充电电流最大1A,充电电压精度高达正负1%,双灯状态指示,外围简单。
本文将介绍ME4052A的对讲机充电应用方案。

LDO和DC/DC有哪些区别?
我们仅从优缺点来做简单的分析 LDO优点:稳定性好,负载响应快。输出纹波小。缺点:效率低,输入输出的电压差不能太大。 DC/DC:直流电压转直流电压。严格来讲,LDO也是DC/DC的一种,但目前DC/DC多指开关电源。具有很多种拓朴结构,如BUCK,BOOST。等优点:效率高,输入电压范围较宽。缺点:负载响应比LDO差,输出纹波比LDO大。 可见LDO只能是降压,DCDC 有升压,降压,升降压多种结构。 由于MOSFET的导通电阻很小,因而它上面的电压降非常低。 如果输入电压和输出电压很接近,最好是选用LDO稳压器,可达到很高的效率。所以,在把锂离子电池电压转换为3V输出电压的应用中大多选用LDO稳压器。虽说电池的能量最后有百分之十是没有使用,LDO稳压器仍然能够保证电池的工作时间较长,同时噪音较低。 如果输入电压和输出电压不是很接近,就要考虑用开关型的DCDC了,应为从上面的原理可以知道,LDO的输入电流基本上是等于输出电流的,如果压降太大,耗在LDO上能量太大,效率不高。 DC-DC转换器包括升压、降压、升/降压和反相等电路。DC-DC转换器的优点是效率高、可以输出大电流、静态电流小。随著集成度的提高,许多新型DC-DC转换器仅需要几只外接电感器和滤波电容器。但是,这类电源控制器的输出脉动和开关噪音较大、成本相对较高。 总的来说,升压是一定要选DCDC的,降压,是选择DCDC还是LDO,要在成本,效率,噪声和性能上比较。
