Description
STA516B is a monolithic quad half-bridge stage in
multipower BCD technology. The device can be
used as dual bridge or reconfigured, by
connecting pin CONFIG to pins VDD, as a single
bridge with double-current capability or as a half
bridge (binary mode) with half current capability.
The device is designed, particularly, to be the
output stage of a stereo all digital high efficiency
amplifier. It is capable of delivering 200 W +
200 W into 6 loads with THD = 10% at
VCC = 51 V or, in single BTL configuration, 400 W
into a 3 load with THD = 10% at VCC = 52 V.
The input pins have a threshold proportional to
the voltage on pin VL.
The STA516B is aimed at audio amplifiers in hi-fi
applications, such as home theatre systems,
active speakers and docking stations.
It comes in a 36 pin PowerSO package with
exposed pad up (EPU).

Warning:
Stresses beyond those listed under “Absolute maximum
ratings” make cause permanent damage to the device. These
are stress ratings only, and functional operation of the device
at these or any other conditions beyond those indicated
under “Recommended operating condition” are not implied.
Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability. In the real
application, power supply with nominal value rated inside
recommended operating conditions, may experience some
rising beyond the maximum operating condition for short
time when no or very low current is sinked (amplifier in mute
state). In this case the reliability of the device is guaranteed,
provided that the absolute maximum rating is not exceeded.

5 Technical information
Technical information
The STA516B is a dual channel H-bridge that is able to deliver 200 W per channel (into
RL = 6 with THD = 10% and VCC = 51 V) of audio output power very efficiently. It operates
in conjunction with a pulse-width modulator driver such as the STA321 or STA309A.
The STA516B converts ternary, phase-shift or 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 protection circuitry.
In differential mode (ternary, phase-shift or binary differential), 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, both full bridge and half bridge modes are supported. The STA516B
includes overcurrent and thermal protection as well as an undervoltage lockout with
automatic recovery. A thermal warning status is also provided.

5.1 Logic interface and decode
The STA516B power outputs are controlled using one or two logic-level timing signals. In
order to provide a proper logic interface, the VL input must operate at the same voltage as
the DDX control logic supply.
