TDA 4862
Functional Description (cont’d)
Undervoltage Lockout
V
An undervoltage lockout circuitry enables the output stage when
reaches the upper
CC
V
V
threshold
and terminates the output stage when
is falling below the lower
CC
CC
. In the standby mode the supply current is typically 75 µA. An internal
V
threshold
CCL
V
clamp has been added from
to ground to protect the IC from an overvoltage
CC
V
condition. The external circuitry is created with a start-up resistor connected from
to
CC
V
the input supply voltage and a storage capacitor from
to ground. Bootstrap power
CC
supply is created with the previous mentioned auxiliary winding and a diode.
Output
The TDA 4862 totem pole output stage is MOSFET compatible. An internal protection
V
circuitry is activated when
is within the stand by mode and ensures that the MOSFET
CC
is turned-OFF. The totem pole output has been optimized to minimize cross conduction
current during high speed operation. The addition of two 4 Ω resistors, one in series with
the source output transistor and one in series with the sink output transistor, reduces the
cross conduction current.
