... The series has a built-in UVLO (under-voltage lock-out) function, therefore, the internal P-channel driver transistor is forced OFF when input voltage becomes 1.8V or lower (for XC9515A, 2.7V or lower). The voltage detector block can be set delay time freely by connecting an external capacitor. With the manual reset function, the series can output a reset signal at any time. ■ ...

... Limit> The current limiter circuit of the XC9515 series monitors the current flowing through the P-channel MOS driver transistor connected to the Lx pin, and features a combination of the current limit mode and the latch mode. ①When the driver current is greater than a specific level (peak value of coil current), the current limit function operates to off the pulses from the Lx pin at any giving timing. ② ...

... The voltage detector block has a manual reset (MR) pin. By setting the MR pin at low level, the low level. By connecting a capacitor (Cd) to the Cd pin, the XC9515 series can set a delay time to V releasing voltage. The delay time can be calculated from the internal resistance, Rdelay (2.5MΩ fixed TYP.) and the value per the following equation ...

... Also the same electrical potential should be applied to the P_V 3. The XC9515 series is designed for use with ceramic output capacitors. If, however, the potential difference between dropout voltage or output current is too large, a ceramic capacitor may fail to absorb the resulting high switching energy and the output could be unstable ...
