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