DI 5V
High side driver control signal: A positive level switches on the high
side
BLx
15, 19,
23
DI 5V
Low side driver control signal: Polarity can be reversed via INV_BL

25
AO 5V
Output of current measurement amplifier
5VOUT
26
Output of internal 5V linear regulator. Provided for VCC supply
SP_SUP
27
A 5V
An external capacitor on this pin controls the commutation spike
suppression time for hallFX.
VCC
28
+5V supply input for digital I/Os and analog circuitry
SENSE_HI
29
DI 5V
Switches current amplifiers to high sensitivity
BBM_EN
30
DI 5V
Enables internal break-before-make circuitry
INV_BL
31
DI 5V
Allows inversion of BLx input active level (low: BLx is active high)
ENABLE

Exposed
die pad
-
GND
Connect the exposed die pad to a GND plane. It is used for cooling
of the IC and may either be left open or be connected to GND.
