7.1.2 Power down
For very low standby power applications the power-down mode can be activated by
pulling the VINSENSE pin below the V
the safe restart protection will be activated. Because the high voltage start-up current
source is also disabled during power-down, the TEA1753LT will not restart until the
VINSENSE pin voltage is raised again. During power down all internal circuitry is disabled
except for a voltage detection circuit on the VINSENSE pin. This circuit is supplied by the
HV pin and will draw 16 μA from the HV pin for biasing.
