Start-up sequence, normal operation and restart sequence
7.1.2 Power down
The power-down mode is activated for very low standby power applications by pulling the
VINSENSE pin below the V th(pd) level. The TEA1753LT stops switching and the safe
restart protection is activated. The high-voltage start-up current source is also disabled
during power-down, so the TEA1753LT does 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 draws 16
? A from the HV pin for biasing.
If the VINSENSE pin is pulled low, a latched protection is also reset. (see Section 7.1.5 )
