DESCRIPTION
STA510 is a monolithic full bridge stage in Multipow-
er BCD Technology. The device is particularly de-
signed to make the output stage of classD audio
amplifier capable to deliver 100W undistorted output
power on 8
load. The input pins have threshold pro-
portional to V
Ibias
pin voltage. The commutation
speed of the output stage is settable with an extenal
resistor (Curref pin) to choice for each application the
best compromise of THD versus EMI and current
spikes.
The overcurrent protection works in two steps, the
first one, at a lower value limits the current terminat-
ing the pulse (independently to the input) when the
current in the power output MOS reaches a first
threshold: it is aimed to act in case of overload and its
effect is to stabilize the mean current in the load to a
limit value. The second step shuts down completely
the device and restarts the power on sequence if the
current reaches a second (higher) threshold: it is
aimed to act in case of short circuit, when the first lim-
itation can fail.
