XC6194AA03ER-G Torex Semiconductor

XC6194 Series ETR33013-002 1A Output Current Push Button Smart Load Switch FEATURES GENERAL DESCRIPTION Input Voltage Range : 1.8V ~ 6.0V The XC6194 series are the Push Button load switch with functions best suitable for battery operated devices. Stand-by Current : 0.001A (TYP.) / Turn-Off state Quiescent Current : 0.13A (TYP.) / Turn-On state The built-in high side switch is turned on by the Push Output Current : 1000mA (V =2.0V, Ta=25) IN Button (Turning off is also possible on the A type.) and Turn-On Delay Time : 0.2s, 1.0s, 3.0s or 5.0s turned off by the level signal into the SHDN pin from the Turn-Off Method : Type A By inputting H voltage to MCU or the like. the SHDN pin. The high side switch is turned on and latched by inputting signal from the Push Button of the device to the SW pin. By inputting L voltage It is possible to shut down (OFF) by inputting a 1-pulse during the T to the SW pin. OFFD signal of level from the MCU or the like to the SHDN pin. Type B By inputting H voltage to This realizes a main switch of battery operated devices the SHDN pin. (*1) easily. Turn-Off Delay Time : 3s, 5s, 10s or 15s Added function Power Good function (The PG pin) The leak current at shutdown is so small, which is 1nA(TYP.), that this IC will contribute to reducing the Shutdown function (the SHDN pin) discharge of the battery and making shelf life longer of the Protective function : Output capacitor inrush current limit soft-start devices after shipping as well as functioning as a main Output capacitor discharge function switch. Output short circuit protection Thermal shutdown For the A type, it is possible to turn off forcibly in case of emergency by Push Button signal. This enables a freezed Operating Ambient Temperature : -40 ~ 85 device to be turned off. For the B type, turn-off is available Package : USP-8B06 (2.0 x 2.0 x h0.33mm) only with SHDN pin. The XC6194 series has a power good function (the PG pin) for properly adjusting the timing of turning on the DC - DC regulator or other downstream system. In addition to these functions, this IC is equipped with output capacitor inrush current limiting function and short- APPLICATIONS circuit protection function, realizing an intelligent load Wearable devices switch. Smart card devices (*1) Please be sure to complete the preparation for shutting down Wireless headphones / Earphones safely before inputting the signal to SHDN pin from the MCU or the IoT devices likes. Applications with ON/OFF switch function Various applications equipped with buttons Various applications equipped with mechanical switches The devices with waterproof function.
