Drive Outputs
The three top drive outputs (Pins 1, 2, 24) are open
collector NPN transistors capable of sinking 50 mA with a
minimum breakdown of 30 V. Interfacing into higher
voltage applications is easily accomplished with the circuits
shown in Figures 24 and 25.
The three totem pole bottom drive outputs (Pins 19, 20,
21) are particularly suited for direct drive of NChannel
MOSFETs or NPN bipolar transistors (Figures 26, 27, 28
and 29). Each output is capable of sourcing and sinking up
to 100 mA. Power for the bottom drives is supplied from V
C
(Pin 18). This separate supply input allows the designer
added flexibility in tailoring the drive voltage, independent
of V
CC
. A zener clamp should be connected to this input
when driving power MOSFETs in systems where V
CC
is
greater than 20 V so as to prevent rupture of the MOSFET
gates.
The control circuitry ground (Pin 16) and current sense
inverting input (Pin 15) must return on separate paths to the
central input source ground.
Thermal Shutdown
Internal thermal shutdown circuitry is provided to protect
the IC in the event the maximum junction temperature is
exceeded. When activated, typically at 170
°
C, the IC acts as
though the Output Enable was grounded.
