Description
STA517B is a monolithic quad half bridge stage in Multipower BCD Technology. The device can be used as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability, and as half bridge (Binary mode) with half current capability.
The device is particularly designed to make the output stage of a stereo all-digital high efficiency (DDX™) amplifier capable to deliver 175 + 175 W @ THD = 10 % at V load and 350 W @ THD = 10 % at V 4 load in single BTL configuration.

Power supply and control sequencing STA517B

4 Power supply and control sequencing

To guarantee correct operation and reliability, a correct turn on/off sequence must be followed. Figure 3 shows the correct power on sequence.

Figure 3. Correct power-on sequence

V
Vcc > V
L
PWRDN
IN
Vcc must turn on before V
in order to prevent uncontrolled current flowing through an
L
internal protection diode connected between V
V
cc
V
L
(logic supply) and Vcc (high power supply).
L
Failure to do so could result in damage to the device.
PWRDN must be released after V
is switched on. An input signal can then be sent to the
L
power stage.
