CAP1133 - Microchip

CAP1133 3 Channel Capacitive Touch Sensor

The CAP1133, which incorporates RightTouch® technology, is a multiple channel Capacitive Touch sensor with multiple power LED drivers. It contains three (3) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input automatically recalibrates to compensate for gradual environmental changes..

Features

• Three (3) Capacitive Touch Sensor Inputs - Programmable sensitivity - Automatic recalibration - Individual thresholds for each button
• Proximity Detection
• Multiple Button Pattern Detection
• Calibrates for Parasitic Capacitance
• Analog Filtering for System Noise Sources
• Press and Hold feature for Volume-like Applica- tions
• SMBus / I2C Compliant Communication Interface
• Low Power Operation - 5uA quiescent current in Deep Sleep - 50uA quiescent current in Standby (1 sensor input monitored) - Samples one or more channels in Standby
• Three (3) LED Driver Outputs - Open Drain or Push-Pu.
