Pin Definitions and Functions
Pin No. Symbol
Function
1SQH2
Squib High-Side Driver for Firing Loop 2; output of the DMOS
high-side switch output.
2SQL2
Squib Low-Side Driver for Firing Loop 2; input of the DMOS
low-side switch input.
3GNDL2
Ground Terminal for Firing Loop 2; directly connected to the
ground terminal of the power reserve capacitor.
4
SEN
Squib Enable; input signal, that must be high during measurement
and firing (see Table 1 on page 9)
5MSR
Measurement Sense Resistor; resistor to ground used for
measurement current to voltage conversion (see Figure 6).
6DI
Serial Data Input; receives data from the
C.
7CLK
Clock Input for SPI.
8CSN
Chip Select Negative; the device is selected if the input is low.
9RI
Reset In; CMOS-level input. Logic high is needed for operation
(see Table 1 on page 9)
10
MO
Measurement Output; diagnostic pin for digital and analog
measurements with an output range from 0 to 5 V (see Figure 6).

CHP
Supply Voltage for high side Gates; Connection terminal to an
external storage capacitor.
V
CHP provides gate to source voltage for
high side driver. If not connected
V
CHP = VBoost - VDiode
15
MCA
Measurement Current Adjust; terminal to an external resistor
R
MCA to ground, which determines the reference measurement
current.
