Pinout Description
(See Connection Diagram)
Pin 1, BOOTSTRAP 1 Input:
Bootstrap capacitor pin for half
H-bridge number 1. The recommended capacitor (10 nF) is
connected between pins 1 and 2.
Pin 2, OUTPUT 1:
Half H-bridge number 1 output.
Pin 3, DIRECTION Input:
See Table 1 This input controls
the direction of current flow between OUTPUT 1 and OUT-
PUT 2 (pins 2 and 10) and, therefore, the direction of rotation
of a motor load.
Pin 4, BRAKE Input:
See Table 1 This input is used to
brake a motor by effectively shorting its terminals. When
braking is desired, this input is taken to a logic high level and
it is also necessary to apply logic high to PWM input, pin 5.
The drivers that short the motor are determined by the logic
level at the DIRECTION input (Pin 3): with Pin 3 logic high,
both current sourcing output transistors are ON; with Pin 3
logic low, both current sinking output transistors are ON. All
output transistors can be turned OFF by applying a logic high
to Pin 4 and a logic low to PWM input Pin 5; in this case only
a small bias current (approximately 1.5 mA) exists at each
output pin.
Pin 5, PWM Input:
See Table 1 How this input (and DIREC-
TION input, Pin 3) is used is determined by the format of the
PWM Signal.
