IQS231A

ProxSense® Series IQS231A Datasheet Single Channel Capacitive Proximity/Touch Controller for SAR applications The IQS231A ProxSense® IC is a self-capacitance controller designed for applications where an awake/activate on proximity function is required. The IQS231A is an ultra-low power solution that uses unique release and/or movement detection for applications that require longterm detection. The IQS231A operates standalone or I2C and features configuration via OTP (One Time Programmable) bits. Switching from I2C to standalone during runtime is also possible in order to access all settings while offering the simplicity of a standalone output. Features  Integrated SAR user interface offering a simple GPIO output  Quick release detection – effectively prevent false triggers  Quick release sensitivity options  Wide range of control for sensing in high power RF environments  Pin compatible with IQS128 and IQS229  1.8V to 3.3V Input voltage  Capacitive resolution down to 0.02fF  Capacitive load capability up to 200pF  External threshold adjustment pin (minimize need for pre-empted OTP adjustments)  Minimal external components (direct input strap)  Standalone failsafe mode (backwards compatible failsafe output, short pulses on output to indicate operational device)  Default OTP options focus on safety and passing SAR lab qualification, OTP changes offer performance advantages  I2C interface option (improved compatibility) RoHS2 Compliant 6 pin TSOT23-6 8 pin WL...
