DESCRIPTION

12, 19

Positive Power Supply pins; internally common and externally connect to the same Positive Supply (V+).

15

Negative Power Supply pin; Negative or Ground return for Switch Driver A; externally connect to the Supply

(V-).

16

Negative Power Supply pin; Negative or Ground return for Switch Driver B; externally connect to the Supply

(V-).

8, 5

A1, B1

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.

9, 3

A2, B2

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.

7, 4

ENA, ENB

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.

14, 17

OUTA, OUTB

Respectively, Switch Driver A and Switch Driver B Output pins.

2

ILF

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.
