灿瑞科技推出OCP9229限流保护芯片,高负载容量(<100µF),为负载线路保驾护航
在当前激烈的市场竞争中,数码产品对成本控制的要求愈发严格。OCS顺应市场需求,在OCP9227(Imax=3.5A)的基础上,推出了小电流产品OCP9229(Imax=2A)。
该产品主要致力于系统对外供电保护,我们将安全性视为设计的核心,因此采用了限流保护芯片,以防止接口或外接设备短路造成的过热和损坏。OCP9229在此方面表现卓越,并在OCP9227的基础上增加了短路保护功能,进一步优化了负载供电端的保护措施。
OCP9229应用场景
CP9229是一款高级负载管理开关,专为需要高度集成解决方案的应用而设计。它具有严格的断开状态电流目标和高负载容量(<100µF),能够有效断开直流电源轨供电的负载。该芯片由一个慢速控制的低阻抗MOSFET开关(典型阻抗78mΩ)和集成模拟功能组成。使能管理通过逻辑输入(高有效)实现,可直接与低压控制信号或通用输入/输出(GPIO)接口连接,无需额外外部下拉电阻。
主要功能OCP9229
1.软起动:回转速率控制的导通特性防止了浪涌电流和由此导致的电源轨上的过度电压降。
2.限流与短路保护:使用不同的ISET对地电阻,可以选择不同的限流,公式为ILIM(A)=1000/RSET(Ω),当电流超过设置限流时,芯片会强制输出电流为设计值,直至触发OTP。或当VOUT电压低于2V时,会引发短路保护,芯片将会关断。在1.6s后打嗝启动。
3.输出过压保护;不同的输出OVP版本(OCP9229A:14.2V,OCP9229C:5.8V),根据OVP版本提供不同的输入电压范围(OCP9229A:2.5V~13.5V, OCP9229C:2.5V~5.5V),支持广泛的消费电源管理应用。
4.真逆流阻塞(TRCB)功能,可在ON和OFF状态下阻挡从VOUT到VIN的不必要逆流。异常低的断开状态电流损耗(最大<2µA)有助于符合备用电源要求。
5.过温保护:当温度超过OTP温度点,芯片将会关断,只到温度低于OTP恢复点再次启动。OCP9229采用完全“绿色”兼容的1.19mm*1.29mm WLCSP-9B封装。
OCP9229广泛应用于手机、平板电脑、笔记本电脑等移动充电设备,为您提供安全可靠的电源保护方案。
