Pushbutton Switches are essential components in electrical and electronic systems such as cameras, telecommunications systems, automobile ignition systems, home appliance power switches and more. Integrated circuit switching devices are used in almost all fields and in most of electronic products. The AML22CBS8BA is an integrated circuit pushbutton switch developed to provide an enhanced and reliable solution to customers’ varied needs.

The AML22CBS8BA integrates a capacitive sensing element, an internal variable gain amplifier, an internal oscillator, bin-wise output current capability, an external resistor for power management, a programmable LED current sink, and an LED brightness control function into a single chip packaged in a small and lightweight miniaturized form factor. The device has two operating modes, analog and digital, and can detect multi-level input signals such as those associated with capacitive touch buttons.

In the analog mode the device can detect capacitive input signals and comes with a full range of I/O pins to support the attachment of multiple external capacitors. An integrated gain amplifier provides fast response to any capacitive change, while an internal oscillator eliminates the need for adjustments. The bin-wise output current capability enables the device to adjust the LED brightness even in low power usage applications.

In the digital mode, the AML22CBS8BA enables the use of external capacitors to detect capacitive input signals. The device has integrated logic and signal processing which can recognize up to 4 distinct states of capacitive touch. An external resistor is used for power management, which greatly decreases power consumption. An external LED current sink is provided to control the LED brightness and the currentrange can be programmed with the external resistor.

The AML22CBS8BA has been designed to work in a range of environments, including automotive and industrial. It is highly durable and resistant to environmental factors such as vibration, shock, temperature, and electrical noise. It is also highly reliable, as it is protected against incorrect wiring, reverse voltage and short-circuiting. Additionally, the AML22CBS8BA is highly efficient, with low power consumption, which helps reduce total system cost.

The AML22CBS8BA is an excellent solution for those requiring an integrated pushbutton switch with high tolerance to environmental disturbances. Its wide range of features, including its two operating modes, internal oscillator, LED current sink and LED brightness control, provide customers with increased functionality and performance. The device is highly reliable, efficient and cost effective, making it the ideal choice for applications requiring a cost effective, robust and highly capable integrated circuit pushbutton switch.
