RM1233AM Description:
RM1233AM-ST6x/DF6x is a single button touch detection chip. This touch detection chip has a built-in voltage regulator circuit, which provides stable voltage for the touch sensing circuit to use. The stable touch detection effect can widely meet the needs of different applications. This touch detection chip is designed to replace traditional buttons, and the size of the touch detection PAD can be designed within a reasonable range according to different sensitivities. Low power consumption and wide operating voltage are the characteristics of this touch chip in DC or AC applications.
RM1233AM Feature:
Working voltage 2.3V~5.5V
Built in voltage regulator circuit provides stable voltage for the detection circuit to use
Built in Low Voltage Reset (LVR) function
Fast mode standby current 3.3uA@VDD =3V, no load
Touchable detection input pin connected to external capacitor (0-10pF) to adjust sensitivity
Output mode selection (TOG): synchronous output or latch output
CMOS Output Effective Level Selection (AHLB): High or Low Level Output Effective
Maximum output time for buttons: 16 seconds or infinity
After being powered on, there is a stable time of about 0.5 seconds
Automatic calibration function, environment adaptive calibration function
Within 8 seconds of power on, the reference value is refreshed approximately once per second. If there are touch keys within 8 seconds of power on or if the keys are not touched after 8 seconds, the recalibration cycle is 4 seconds
DFN-6L, SOT23-6L packaging
RM1233AM Application scope:
Various consumer products
Replace button keys
