Adjustable sensitivity using an external capacitor (1-50 pF). The below image is showing the standard interfacing of the touch sensor. Cherry on top that LCSC mark this chip as discontinued, so I need alternatives. Operating current 2.0uA for 8-key mode. All output modes can be configurable for high or active low by pad options. The IC uses an onboard sense pad that uses copper trace as a touch element and the touch sensitivity can be configured using an additional external capacitor ranging from 0 to 50pF. Features TONTEK TonTouch touch pad detector IC TTP229-LSF, supports up to 16 keys with adjustable sensitivity and built-in LDO The system re-calibrates automatically when all keys are not detected touch more than about 4 seconds 8 keys OR 16 keys option single-key OR multi-kye feature SKU: 1176 | DAB652 Stock: 65. The TTP229 IC uses the I2C-bus slave interface data transmission protocol to output the data of the touch pads (TP0~TP15 pins), so the TTP229 only accepts the read operation that R/W bit is〝 1 〞. The TTP229 touch controller is the exact noncontact alternative of traditional button switches or matrix keypads. Stable sensing method can cover diversity conditions. The TTP229-BSF TonTouchTM IC is capacitive sensing design specifically for touch pad controls. 16 or 8, whatever inputs are used, the IC features fewer component counts during the integration in the system. active high or active low by option (TOG/AHLF/OD pin). Write review. The TTP223 is a touch pad detector IC which offers one touch key, designed for replacing traditional direct key button switch with diverse pad size. TTP229 is an 8 to 16-channel touch detector IC that could be used as an 8 to 16 touch key driver. The IC can handle 8 or 16 touch buttons and supports single and multi-key options. Provides direct mode or toggle mode, CMOS output, or open-drain output. It has a built in regulator so it offers stable sensing to cover various conditions. Provides fast mode and low power mode selection by pad optional (LPMB pin). Human datasheet search, datasheets, Datasheet search site for … The touching detection IC is designed for replacing traditional direct button key with diverse pad size. I’ll keep you posted. It is a useful device when replaced with a traditional button key. TTP226 Touch Sensor ICThe TTP226 is a touch pad detector IC which offers 8 touch keys. Direct mode and Toggle mode selection pin available. The TTP223-BA6 is a touch pad detector IC which offers 1 touch key. If it is〝 0 〞, the TTP229-LSF will not respond the write operation.

The major advantage of TTP229 is that it could replace the standard 8-key matrix keypad. Provides one output pin TPQ0D that has no diode protection circuit inbuilt and it is. The IC uses group functions where 4 groups are available in 16-bit mode and 2 groups are available in 8-bit mode. This guide helps you understand the Capacitive Touch Sensor IC TTP229 very easily and use it in your peojects. At the heart of the circuit is an inexpensive (`20) smd chip TTP223 commonly available in BA-6 package. Next in the series is the 16 key touch pad module built around the TTP229 chip. 16-key data can be read using serial interface. endstream endobj 104 0 obj<> endobj 105 0 obj<> endobj 106 0 obj<> endobj 107 0 obj<>stream Single Channel Capacitive Touch Sensing IC. 1. TTP229 is an 8 to 16-channel touch detector IC that could be used as an 8 to 16 touch key driver. Note: Complete technical details can be found in the TTP229 Datasheet, linked at the bottom of this page. 16-key board TTP229 capacitive touch sensor IC 2. onboard power indicator 3. working voltage: 2.4V-5.5V 4. the module can be set to output mode, the key output mode, the longest time and fast output / … TTP229 16-Channel Digital Capacitive Switch Touch Sensor Module Onboard TTP229 capacitive 16-key touch sensing IC Onboard power indicator Working voltage: 2.4V-5.5V Module can set output mode, key output mode, longest It has a, Operating voltage - 2.4V - 5.5V for built-in regulator mode, Operating voltage - 2.0V - 5.5V for built-in regulator disabled. This board is a quick demo board for capacitive touch sensing IC TTP229. The IC uses group functions where 4 groups are available in, Place the Sense pads as close as possible to the IC, Use the proper filter and bypass capacitor to reduce noises or ripple in the input supply. It has an auto-calibration feature for life and it has a re-calibration period of about 4.0 seconds. It features 16 sensitive touch pads that make an ideal replacement for the old fashioned keypads. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. It requires basic components followed by the sense pads. Use an X7R or NPO rated capacitor for better accuracy over a wide temperature. It also allows the user to group the keys. Low power consumption and wide operating voltage are the contact key features for DC or AC application. So we have to use the other approach, but that’s not too bad after the insight that the main advantage of having multiple pads on one I2C bus is not an option due to the inability to select other addresses for the keypad. Place the capacitor C2 as close as possible. The TTP229 IC can independently handle the 8 touch pads or up to 16 touch pads. It has a built-in regulator for the touch sensors that enable stable sensing in diverse conditions.
