S-GND
Sense ground
4, 25
SUBGND
IC sub-ground
23
7
D-GND
Low side built-in diode ground (anode side)
8
CR
Chopping is performed at the period of a triangle wave set by the RC circuit connected to this pin.
The triangle wave off time is the noise cancellation time.
16

VREF1
VREF2
Output current settings.
(The output current is determined by providing an input in the range 1.5V to 5V.)

PHASE1
PHASE2
Output phase switching inputs
High-level input: OUTA = high, OUTA = low
Low-level input: OUTA = low, OUTA = high
19

ENABLE1
ENABLE2
Output on/off control inputs
High-level input: Output off
Low-level input: Output on
17, 18
