The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2μA. The PW4055 can be put into shutdown mode, reducing the supply current to 25μA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage

電子書-RTL Design Style Guide for Verilog HDL540頁A FF having a fixed input value is generated from the description in the upper portion of Example 2-21. In this case, ’0’ is output when the reset signal is asynchronously input, and ’1’ is output when the START signal rises. Therefore, the FF data input is fixed at the power supply, since the typical value ’1’ is output following the rise of the START signal. When FF input values are fixed, the fixed inputs become untestable and the fault detection rate drops. When implementing a scan design and converting to a scan FF, the scan may not be executed properl not be executed properly, so such descriptions , so such descriptions are not are not recommended. recommended.[1] As in the lower part of Example 2-21, be sure to construct a synchronous type of circuit and ensure that the clock signal is input to the clock pin of the FF. Other than the sample shown in Example 2-21, there are situations where for certain control signals, those that had been switched due to the conditions of an external input will no longer need to be switched, leaving only a FF. If logic exists in a lower level and a fixed value is input from an upper level, the input value of the FF may also end up being fixed as the result of optimization with logic synthesis tools. In a situation like this, while perhaps difficult to completely eliminate, the problem should be avoided as much as possible.
