Positive Power Supply pins; internally common and externally connect to the same Positive Supply (V+).
Negative Power Supply pin; Negative or Ground return for Switch Driver A; externally connect to the Supply
(V-).
Negative Power Supply pin; Negative or Ground return for Switch Driver B; externally connect to the Supply
(V-).
Common Ground pin for the Input Logic Control circuits. May be used as a common ground with V SSA and
V
Input pins used to control the direction of output load current to/from OUTA and OUTB, respectively. When
connected, A1 and B1 can be controlled from the same logic signal to change the directional rotation of a
motor.
Input pins used to force a low state on OUTA and OUTB, respectively. When connected, A2 and B2 can be
controlled from the same logic signal to activate Dynamic Braking of a motor.
Input pins used to Enable Switch Driver A and Switch Driver B, respectively. When Low, the respective
output is in a high impedance (Z) off-state. Since each Switch Driver is independently controlled, OUTA and
OUTB may be a separately PWM controlled as Half H-Switch Drivers.
Respectively, Switch Driver A and Switch Driver B Output pins.
Current Limiting Fault Output Flag pin; when in a high logic state, signifies that Switch Driver A or B or both
are in a Current Limiting Fault Mode.
