Pin Function
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 = 2.5 × VC. There
are no limitations on the magnitude
relationships between the VCC and VC
supply voltages.
2
ENA
Standby/drive control input pin.
Current drain in standby mode is 10 A or
less.
L: –0.3 to + 0.7 V or open
H: 3.0 to 9.0 V
There are no limitation on the magnitude
relationships between VCC and VENA
supply voltage.
7VM
Control input pin for switching between
constant voltage output and saturated
output.
L: –0.3 to VCC 2.5 V
(saturated output)
H: VCC 0.3 to VCC or open
(constant-voltage regulated output)
Sample Application Circuit
If the outputs oscillate, insert capacitors
of 0.001 to 0.1 F between the outputs.
