DESCRIPTIONSTA506A is a monolithic quad half bridge stage in
Multipower BCD Technology.
The device can be used as dual bridge or reconfig-
ured, 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 out-
put stage of a stereo All-Digital High Efficiency
(DDX™) amplifier capable to deliver 60 + 60W @
THD = 10% at Vcc 32V output power on 8Ω load and
80W @ THD = 10% at VCC 36V on 8Ω load in single
BTL configuration. In single BTL configuration is also
capable to deliver a peak of 120W @THD = 10% at
VCC = 32V on 4Ω load. The input pins have threshold
proportional to VL pin voltage.

Table 3. Functional Pin Status(*) : The pin is open collector. To have the high logic value, it needs to be pulled up by a resistor.
(**): To put CONFIG = 1 means connect Pin 24 (CONFIG) to Pins 21, 22 (Vdd) to implement single BTL (mono mode) operation for
high current.

STA506A TECHNICAL INFO: The STA506A is a dual channel H-Bridge that is able to deliver more than 60W per channel (@ THD=10%) of
audio output power in high efficiency.
The STA506A converts both DDX and binary-controlled PWM signals into audio power at the load. It includes
a logic interface , integrated bridge drivers, high efficiency MOSFET outputs and thermal and short circuit pro-
tection circuitry.
In DDX mode, two logic level signals per channel are used to control high-speed MOSFET switches to connect
the speaker load to the input supply or to ground in a Bridge configuration, according to the damped ternary
Modulation operation.
In Binary Mode operation , both Full Bridge and Half Bridge Modes are supported. The STA506A includes over-
current and thermal protection as well as an under-voltage
Lockout with automatic recovery if FAULT and TRISTATE pins are connected together to an external capacitor,
as in fig.9

3.1 Logic Interface and Decode:The STA506A power outputs are controlled using one or two logic level timing signals. In order to provide a prop-
er logic interface, the VL input must operate at the dame voltage as the DDX control logic supply.
3.2 Protection Circuitry:The STA506A includes protection circuitry for over-current and thermal overload conditions. A thermal warning
pin (pin.28) is activated low (open drain MOSFET) when the IC temperature exceeds 130°C, in advance of the
thermal shutdown protection. When a fault condition is detected , an internal fault signal acts to immediately
disable the output power MOSFETs, placing both H-Bridges in high impedance state. At the same time an open-
drain MOSFET connected to the fault pin (pin.27) is switched on.
