STA518-40 V, 3.5 A quad power half-bridge
The STA518 is a monolithic quad half-bridge
stage in multipower BCD technology. The device
can be used also as dual bridge or reconfigured,
by connecting the CONFIG pin to the Vdd pin, as
a single bridge with double current capacity.
The device is particularly designed to make the
output stage of a stereo all-digital high-efficiency
(DDX™) amplifier capable of delivering an output
power of 24 W x 4 channels @ THD = 10% at
VCC 30 V into a 4 load in single-ended
configuration.
It can also deliver 50 + 50 W @ THD = 10% at
VCC 29 V as output power into an 8 load in BTL
configuration and 70 W @ THD = 10% at VCC 34 V into 8 in a single paralleled BTL
configuration.
The input pins have a threshold proportional to
the VL pin voltage.
