MC11S

Mysentech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · QFN-16(3x3)

MC11S from Mysentech, in a QFN-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SCL input I2C serial clock input. Standard mode up to 400 kHz, fast mode up to 1000 kHz. Requires an external pull-up resistor to VDD.
2 SDA bidirectional I2C serial data line (bidirectional, open-drain). Requires an external pull-up resistor to VDD.
3 CLKIN input External counter clock input, 0.1 MHz to 50 MHz with 40-60% duty cycle. Tie to GND when the internal 2.4 MHz clock is selected via REF_CLK_SEL.
4 ADDR input I2C slave address select input. Ties the device address to one of the supported values depending on the logic level applied.
5 INTB output Interrupt / alert output, active low. Signals conversion-complete or alarm status depending on configuration.
6 SD input Shutdown-mode enable input. Tie to GND when not used; drive high to force the chip into shutdown for lowest current (~40 nA).
7 VDD power_in Supply voltage, 2.0 V to 5.5 V (absolute max 5.5 V). Typical measurement peak current 0.8 mA, average 2.6 µA @ 1 Hz sample rate.
8 GND power_in Device ground reference.
9 NC unconnected No connection. Leave floating.
10 NC unconnected No connection. Leave floating.
11 NC unconnected No connection. Leave floating.
12 VT output Analog negative-temperature-coefficient voltage output. Read externally by MCU ADC to derive die temperature for temperature compensation.
13 C1N passive Channel 1 differential capacitive sense input (negative). Connects to the reference/second sensing capacitor; measures up to 1000 pF, driver current up to 3.2 mA per channel.
14 C1P passive Channel 1 differential capacitive sense input (positive). Paired with C1N; typically used for the reference capacitor in differential mode.
15 C0P passive Channel 0 differential capacitive sense input (positive). Paired with C0N; typically used for the sensed (DUT) capacitor.
16 C0N passive Channel 0 differential capacitive sense input (negative). Paired with C0P for the sensed capacitor connection.
