Note: Be sure to set the pin PWM to High when the PWM control function is not used.

Standby Circuit
All circuits are turned off except the standby circuit and the charge pump circuit under the standby
condition.
The input voltage range is shown below. Input at CMOS and TTL level is possible. The input signal has
0.2 V (typ.) hysteresis.
VINSH: 2 to Vreg V
VINSL: GND to 0.8 V
Do not attempt to the control the output by inputting PWM signals to the standby pin. Doing so may
cause the output signal to become unstable, resulting in destruction of the IC.
The charge pump circuit is turned ON/OFF by the switch of the input signal from the standby pin. If
the switching cycle is shorter than 50 ms, the charge pump circuit will not operate with precise timing.
Therefore the switching cycle of the standby pin should be longer than 50 ms.
When the Standby condition is changed to Operation Mode, set IN1 and IN2 to Low level (Stop Mode) at
first. Then switch IN1 and IN2 to High level when the charge pump circuit reaches the stable condition,
i.e., when VcpA is about VCC + 5 V.
