7 Pin Configuration and Functions

GUID-20210512-CA0I-KSPC-FC1C-58GTLN3JTJ6K-low.gif Figure 7-1 ISOW104420-pin DFMTop View
Table 7-1 Pin Functions
PIN I/O DESCRIPTION
NAME NO.
VIO 1 -- Side 1 Logic supply
IN 2 I General purpose logic (GPIO) input (internal pull-down)
TXD 3 I Driver enable. If this pin is floating, the driver is disabled (internal pull-down)
STB 4 I Standby enable. Connect this pin to GNDIO in normal mode. If this pin is floating or logic high, driver is in standby mode.
RXD 5 O Receiver data output
GNDIO 6 -- Ground connection on side 1 for VIO. GNDIO and GND1 are not internally connected and need be shorted on PCB.
NC 7 -- Not connected internally
EN/FLT 8 I/O

Multi-function power converter enable input pin or fault output pin. Can only be used as either an input pin or an output pin.

  • If it's used as Power converter enable input pin, it enables and disables the integrated DC-DC power converter. Connect directly to microcontroller or through a series current limiting resistor to use as an enable input pin. DC-DC power converted is enabled when EN is high (connected to VIO) and disabled when low (connected to GND1). If EN is floating, DC-DC converter is enabled (internal pull-up resistor)
  • If it's used as Fault output pin, it gives an alert signal if power converter is not operating properly. This pin is active low. Connect to microcontroller through a 5 kΩ or greater pull-up resistor in order to use as a fault outpin pin.
VDD 9 -- Side 1 DC-DC converter power supply
GND1 10 -- Ground connections on side for VDD . GNDIO and GND1 are not internally connected and need be shorted on PCB.
GND2 11 -- Ground connections on side for VISOOUT . GND2 and GISOIN are not internally connected and need be shorted direclty on PCB, or connected through a ferrite bead.
VISOOUT 12 -- Isolated power converter output voltage. VISOOUT and VISOIN need be shorted directly on PCB, or connected through a ferrite bead.
VSIN 13 I Power converter input . Pin 12 and pin 13 need be shorted directly on PCB.
OUT 14 O General purpose logic (GPIO) output (default output is low)
GISOIN 15, 16, 17 -- Ground connections for VISOIN. GND2 and GISOIN need be shorted direclty on PCB, or connected through a ferrite bead.
CANL 18 I/O Low-level CAN bus line
CANH 19 I/O High-level CAN bus line
VISOIN 20 -- Power supply input for CAN tranceiver. VISOIN and VISOOUT need be shorted direclty on PCB, or connected through a ferrite bead.
