{"title":"Qwiic Power Switch","handle":"sparkfun-qwiic-power-switch","url":"/products/sparkfun-qwiic-power-switch","description":"This compact Qwiic board lets you switch power to downstream Qwiic devices so high-current modules can be turned off when they are not needed. That can help conserve energy in battery-powered builds using GNSS and other power-hungry Qwiic boards.It also provides I2C bus isolation, so slower 100kHz devices can sit in the same project as faster 400kHz devices without forcing the whole bus to run slowly. The board has IN and OUT Qwiic ports, plus pull-up resistor and power LED jumpers for configuring low-power use.Two extra GPIO pins are available as inputs or outputs for controlling other parts of your project. It works with the SparkFun Qwiic Mux for controlling and powering multiple devices, including devices that share the same I2C address.SparkFun provides an Arduino library with examples for power switching, bus isolation and GPIO control, along with supporting design files and datasheets.Features:PCA95364-Bit I2C to Parallel Port ExpanderInput/Output Configuration RegisterPolarity Inversion RegisterInternal Power-On ResetNo Glitch on Power UpPCA9306Dual Bidirectional I2C Bus Voltage-Level TranslatorLockup-free Operation for IsolationDMG2305UX: P-Channel MOSFETIN and OUT Qwiic Connection PortsIN and OUT I2C Pull-Up Resistors2x Extra GPIO PinsIN and OUT Power LEDsCan be disabled for low power applicationsJumpersIN power LEDOUT power LEDIN I2C Pull-Up ResistorsOUT I2C Pull-Up ResistorsSpecifications:Operating Voltage (VCC): 2.3V to 5.5VNote: Qwiic operation must be limited to 3.3VOperating Temperature: -40°C to +85°CI2C Bus: 400kHz Fast I2C BusStandby Current Consumption (Typical): 0.2μAI2C Address: 0x41On-resistance: 52mΩ (0.052 Ohms) typical on-resistanceBoard Dimensions: 1.0in. x 1.0in.
