In addition, 1.0V regulator and 1.1V low battery alarm functions are provided.POWER-DOWN FUNCTIONThe entire receiver IC may be powered up and down through the control of the BS input (pin13). During power down operation, the quiescent current consumption of the IC drops to approximately 0µA. The high input impedance of the BS pin allows for direct interfacing with the CMOS output of an off-chip micro controller.CHARGE / DISCHARGE CIRCUITRYThe function of the charge / discharge circuitry is for both fast and slow charging / discharging of the capacitor used for storing the voltage reference level of the FSKREF pin. The CHARGE input (pin14) should be enabled (CHARGE=high=fast charge) immediately after transition of the receiver IC from power-down to normal operation in order to reduce the charging / discharging time for coarse adjustment of the FSKREF voltage to the appropriate dc level (i.e. dc level of LPFOUT pin) and consequently to minimize the erroneous output of the 1-bit comparator. During actual data reception, the CHARGE pin should be set to low (CHARGE=low=slow charge) for fine adjustment of the FSKREF voltage.1-bit COMPARATORThe integrated 1-bit comparator operates as a data slicer and “squares up” the bit-rate filtered output from the quadrature demodulator. The decision threshold voltage level for the 1-bit comparator is stored on an external capacitor connected to the FSKREF pin.REGULATORThe on-chip 1.0V regulator requires a suitable off-chip PNP transistor to achievc regulation. The external PNP transistor should have an hFE>200 for V CE>=0.1V.LOW BATTERY ALARMThe low battery alarm output, ALM, is normally low, but rises to 1.1V (=VCC) when the VCC voltage falls below approximately 1.1V.UTC UNISONIC TECHNOLOGIES CO., LTD. 4QW-R103-015,AUTC TA31142 LINEAR INTEGRATED CIRCUITUTC UNISONIC TECHNOLOGIES CO., LTD.5QW-R103-015,ATYPICAL CHARACTERISTICSUTC TA31142LINEAR INTEGRATED CIRCUITUTC UNISONIC TECHNOLOGIES CO., LTD.6QW-R103-015,ATEST CIRCUIT。

BM 半导体产品选用指南

BM 半导体产品选用指南( 中文版 ---- 技术篇 )引言: 作为电源管理的IC 设计公司, 我们瞄准LCD 市场和网络通讯市场的需求, 给客户提供完整的电源管理解决方案, 让客户安心, 省心的享受电子终端产品的设计和制造乐趣. 本文为技术简介, 献给工程师朋友, 最开始的合理的设计定型对整机的性能和整机的成本具有决定性影响, 设计完之后采购要大比例的杀价降成本有点迟了, 通常只有牺牲的是品质和性能了, 所以设计选型的时候是最重要的, 所以以此为出发点, 写此文供您参考!1． LDO2． DC/DC3．其他4．包装规范LDO由于在各种电子产品中，主控制或相关芯片需要各种各样的供电电压，各种电压转换芯片应运而生。

线性稳压器(由内部的调整电路来完成, 内部没有开关振荡电路)有如下四种：1． 78 系列（或317）。

绝大多数电源管理的芯片产厂家都有，他们的应用广泛，用量大，价格便宜,缺点是静态电流大,10mA左右,输入输出压差高。

例如7805 需要+7.5V 输入才能稳定的输出5V，电流超过0.75A 时，芯片需要很大的散热器。

TO252 的贴片7805 是我们的特色。

我们的型号是BM7805AS,是标准1A的,市面上ＣＪ78M05都是０．５Ａ还不到．但是价格敏感，所以特地为数字高频头的５Ｖ供电做了一颗０．７Ａ的ＢＭ７８Ｄ０５，＋１８Ｖ耐压. 2． BIPOLAR LDO （双极型低压差稳压器）。

是为了降低78系列的输入输出压差而发展的。

一般的这种IC 的压差为1.1V~1.2V 左右，静态电流为8-9 mA左右。

按电流分有如下几种（BM 半导体的）：A．BM1117 1A 的输出，输出有可调的（ADJ），输出从1.25V 基准输出电压起调。

还有输出固定的5.0V , 3.3V , 2.5V , 1.8V 等。

不同于其他公司的产品，BM1117 的输入电压最高可以达+18V ，有些台湾和内地设计的1117 为了价格竞争，输入电压最大只有+8V，输出电流只有800mA，当遇到电压突波时，可能会烧毁，给最终的产品（如DVD 和DVB 等）埋下返修率高的隐患。
