XC6193AA10ER-G Torex Semiconductor

XC6193 Series ETR33013-002 Push Button Smart Load Switch with 140m internal high-side switch and ex ternal Pch MOSFET control pin(GATE pin). FEATURES GENERAL DESCRIPTION Input Voltage Range : 1.8V ~ 6.0V The XC6193 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 Button Output Current : Only Internal FET - 1000mA (V =2.0V) IN (Turning off is also possible on the type.) and turned off by External FET - Depend on FET the level signal into the SHDN pin from the MCU or the Turn-On Delay Time : 0.2s, 1.0s, 3.0s or 5.0s like. Turn-Off Method : Type A By inputting H voltage to The high side switch is turned on and latched by inputting signal from the Push Button of the device to the SW pin. the SHDN pin. It is possible to shut down (OFF) by inputting a 1-pulse By inputting L voltage signal of level from the MCU or the like to the SHDN pin. during the T to the SW pin. OFFD This realizes a main switch of battery operated devices Type B By inputting H voltage to (*1) easily. (The XC6193 series are possible to control not the SHDN pin. only the built-in high side switch but also the external Pch Turn-Off Delay Time : 3s, 5s, 10s or 15s MOSFET.) Added function : External MOSFET Control function The leak current at shutdown is so small, which is (The GATE pin) 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 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. In addition to the built-in high side switch, the XC6193 series has the GATE pin for driving an external Pch MOSFET. APPLICATIONS In addition to these functions, this IC is equipped with output capacitor inrush current limiting function and short- Wearable devices circuit protection function, realizing an intelligent load switch. Smart card devices Wireless headphones / Earphones (*1) Please be sure to complete the preparation for shutting down IoT devices safely before inputting the signal to SHDN pin from the MCU or the Applications with ON/OFF switch function likes. Various applications equipped with buttons Various applications equipped with mechanical switches The devices with waterproof function.
