Table 3.
1. Also connected at the output drain of the overcurrent and thermal protection MOSFET. Therefore, it must be driven putting
in series a resistor with a value in the range of 2.2 kΩ - 180 kΩ, recommended 100 kΩ.

Bridge B source pin. This pin must be connected to power ground
through a sensing power resistor.
Bridge B current controller reference voltage. Do not leave this pin
open or connected to GND.
Step mode selector. High logic level sets half step mode, low logic
level sets full step mode. If not used, it must be connected to GND or
+5 V.
Decay mode selector. High logic level sets slow decay mode. Low
logic level sets fast decay mode. If not used, it must be connected to
GND or +5 V.
Chip enable. Low logic level switches off all power MOSFETs of both
bridge A and bridge B. This pin is also connected to the collector of
the overcurrent and thermal protection to implement overcurrent
protection. If not used, it must be connected to +5 V through a
resistor.
Bootstrap voltage needed for driving the upper power MOSFETs of
both bridge A and bridge B.
Bridge B output 2.
Bridge A power supply voltage. It must be connected to the supply
voltage together with pin VSB.
Bridge B power supply voltage. It must be connected to the supply
voltage together with pin VS
Bridge A output 2.
Charge pump oscillator output.
Reset pin. Low logic level restores the home state (state 1) on the
phase sequence generator state machine. If not used, it must be
connected to +5 V.
Bridge A current controller reference voltage. Do not leave this pin
open or connected to GND.
