Diodes ZXSC310 - Manual (Page 12)

Shutdown Control
The ZXSC310 offers a shutdown mode that produces a
standby current of less than 5uA when in operation.
When the voltage at the S
TDN
pin is 0.7V or higher the
ZXSC310 is enabled, hence the driver is in normal
operation. When the voltage at the S
TDN
pin is 0.1V or
lower the ZXSC310 is disabled, hence the driver is in
shutdown mode. If the S
TDN
pin is open circuit the
ZXSC310 is also enabled.
