Function Pin Description
Supply Voltage (Vcc)
This terminal is the input supply for the analog circuits, typically 5 V +5%/-10% tolerant. A noise filter
capacitor of 4.7
μF (typical) is required on this terminal to ensure stability of the internal circuits.
Ground (Gnd)
This terminal is connected to the system ground.
Ground (DGnd)
This terminal is connected to the system ground.
ADC Reference Voltage (VccA)
This terminal is the input reference for the ADC, typically 5 V. A noise filter capacitor of 0.1
μF (typical) is
required on this terminal to ensure stability of the internal circuits.
Supply Voltage (Vdd)
This terminal is the input supply for the digital circuits, typically 5-V tolerant. A capacitor of 4.7
μF (typical) is
required on this terminal to ensure stability of the internal circuits.
ADC Reference Voltage (GNDA)
This terminal is the input reference for the ADC, typically 0 V.
Gauge OUTPUT (SIP)
The SIP is a positive sensor output. This is the input to the amplifier used for the signal conditioning.
Gauge OUTPUT (SIN)
The SIN is a negative sensor output. This is the input to the amplifier used for the signal conditioning.
Data Input/Data Output (DI/DO)
The DI and DO is the UART communication interface, reporting information back to the microprocessor. This
is an open-drain output with the output set to high-impedance mode when other DO in the system is
activated. The output is by default in RX mode.
Reference Supply (REFI)
Internally generated reference voltage appears as resistor (10 k
) is connected to this pin to set up
reference current for internal oscillator.
Internal oscillator frequency fosc = 2 × (VBG/R) / (VBG ×Ctrim)
VBG = Bandgap voltage (VREFI)
Ctrim = Internally trimmed capacitor
EEPROM Supply (PROGV)
This terminal is the supply for EEPROM program. A capacitor of ~1 nF is required on this terminal.
