XC8115/XC8116 Series
ETR33027-001a 6 V, 1A Ultra-Low Power Load Switch IC ■ GENERAL DESCRIPTION The XC8115/XC8116 series are load switch IC with an integrated Pch MOSFET. As protection functions, it incorporates thermal shutdown, short-circuit protection, and soft-start (inrush current prevention). The soft-start time can be adjusted using an external capacitor. By applying a voltage to the EN pin, the IC can be set to stand-by mode. The EN pin input logic can be selected as either active-high or active-low. The XC8115 series integrates a CL discharge function. The VOUT pin quickly returns to the VSS level when in stand-by. The XC8116 series features reverse current protection, preventing reverse current flow when a voltage higher than VIN is applied to VOUT during stand-by. ■ APPLICATIONS ■ FEATURES Wearable devices Input Voltage : 1.1 V ~ 6.0 V Industrial equipment Output Current : 1A IoT devices ON Resistance : 150mΩ @ VIN=3.6V Quiescent Current : 0.0μA Stand-by Current : 0.0μA Function : CL Discharge (XC8115) Reverse protection at OFF(XC8116) Protective function : Soft Start (external adjustment) Short-circuit protection Thermal shutdown function Operating Ambient : -40°C ~ 105°C Package : DFN1515-6A (1.5 x 1.5 x 0.38mm) SOT-25 (2.8 x 2.9 x 1.3mm) Environmental Consideration : EU RoHS Compliant, Pb Free ■ TYPICAL APPLICATION CIRCUIT
