STA516B
65 V, 7.5 A quad power half bridge
Datasheet
-
production data
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
V
CC
= 51 V or, in single BTL configuration, 400 W
into a 3
load
with THD = 10% at V
CC
= 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.
