ISO1H811G
Pin Configuration and Functionality
1.2 Pin Functionality
VCC (Positive 3.3/5V logic supply)
The VCC supplies the input interface that is
galvanically isolated from the output driver stage. The
input interface can be supplied with 3.3/5V.
DIS
(Output disable)
The high-side outputs OUT0...OUT7 can be
immediately switched off by means of the low active pin
DIS
that is an asynchronous signal. The input registers
are also reset by the DIS
signal. The Output remains
switched off after low-high transition of DIS
signal, till
new information is written into the input register.
Current Sink to GNDCC.
CS
(Chip select)
The system microcontroller selects the ISO1H811G by
means of the low active pin CS
to activate the parallel
interface. By connecting the CS
pin and WR pin to
ground the parallel direct control is activated. Current
Source to VCC.
WR
(Parallel write)
In parallel mode data at the input pins (D0 ... D7) are
latched by means of the rising edge of the low active
signal WR
(write). Current Source to VCC.
D0 ... D7 (Data input bit0 ... bit7)
The present data can be latched on the rising edge of
the write signal WR
. D0 ... D7 control the corresponding
output channels OUT0 ...OUT7. By connecting CS
and
WR
to ground, the signals at D0 ... D7 directly control
the outputs. Current Sink to GNDCC.
DIAG
(Common diagnostic output)
The low active DIAG
signal contains the OR-wired
information of the separated overtemperature detection
units for each channel.The output pin DIAG
provides an
open drain functionality. A current source is also
connected to the pin DIAG
. In normal operation the
signal DIAG
is high. When overtemperature or Vbb
below ON-Limit is detected the signal DIAG
changes to
low.
GNDCC (Ground for VCC domain)
This pin acts as the ground reference for the input
interface that is supplied by VCC.
GNDbb (Output driver ground domain)
This pin acts as the ground reference for the output
driver that is supplied by Vbb.
OUT0 ... OUT7 (High side output channel 0 ... 7)
The output high side channels are internally connected
to Vbb and controlled by the corresponding data input
pins D0 ... D7 in parallel mode.
TAB (Vbb, Positive supply for output driver)
The heatslug is connected to the positive supply port of
the output interface.
