Equivalent Circuit Diagram
Pin Function
14
VCC
Power supply pin for output and controller.
9
12
GND
GND pins for output and controller. Both
must be grounded.
3
6
IN2
IN1
Input pins that determine the excitation of
the outputs.
IN1 control outputs OUT1 and OUT2; IN2
control outputs OUT3 and OUT4.
L: –0.3 to +0.7 V
H: 3.0 to 9.0 V
There are no limitations on the magnitude
relationships between the VCC and VIN
supply voltages.
8
10
11
13
OUT4
OUT3
OUT1
OUT2
Output pins.
Have built-in spark killer diodes.
4
Vref
Reference voltage (= 2.0 V).
5VC
Output
Input pins that determine the constant-
voltage regulated output level.
The constant-voltage regulated output VO
(= voltage between H side output and
GND) is controlled by VO =2.5xVC. There
are no limitations on the magnitude
relationships between the VCC and VC
supply voltages.
2
ENA
Standby/drive control input pin
Current consumption in standby mode is
10 A or less.
L: –0.3 to + 0.7 V
H: 3.0 to 9.0 V
1
7
VM1
VM2
Output
Output voltage setting
Control input pin for switching between
constant voltage output and saturated
output. There are no limitations on the
magnitude relationships between the VCC,
VM1 and VM2 supply voltages.
L: –0.3 to + 0.7 V
(constant-voltage regulated output)
H: 3.0 to 9.0 V (saturated output)
