Azoteq IQS231A
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.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
