PIN TYPE DESCRIPTION
NO. NAME
1 DCDC_OUT Power High-side output of the isolated DC/DC converter; connect this pin to the HLDO_IN pin.(1)
2 DCDC_HGND High-side power ground High-side ground reference for the isolated DC/DC converter; connect this pin to the HGND pin.
3 HLDO_IN Power Input of the high-side LDO; connect this pin to the DCDC_OUT pin(1)
4 NC — No internal connection; connect this pin to HGND or leave this pin unconnected.
5 HLDO_OUT Power Output of the high-side LDO.(1)
6 INP Analog input Noninverting analog input. Either INP or INN must have a DC current path to HGND to define the common-mode input voltage.(2)
7 INN Analog input Inverting analog input. Either INP or INN must have a DC current path to HGND to define the common-mode input voltage.(2)
8 HGND High-side signal ground High-side analog ground; connect this pin to the DCDC_HGND pin.
9 GND Low-side signal ground Low-side analog ground; connect this pin to the DCDC_GND pin.
10 OUTN Analog output Inverting analog output.
11 OUTP Analog output Noninverting analog output.
12 VDD Low-side power Low-side power supply.(1)
13 LDO_OUT Power Output of the low-side LDO; connect this pin to the DCDC_IN pin. The output of the LDO must not be loaded by external circuitry.(1)
14 DIAG Digital output Active-low, open-drain status indicator output; connect this pin to the pullup supply (for example, VDD) using a resistor or leave this pin floating if not used.
15 DCDC_GND Low-side power ground Low-side ground reference for the isolated DC/DC converter; connect this pin to the GND pin.
16 DCDC_IN Power Low-side input of the isolated DC/DC converter; connect this pin to the LDO_OUT pin.(1)
