description
The TPIC6B273 is a monolithic, high-voltage,
medium-current, power logic octal D-type latch
with DMOS-transistor outputs designed for use in
systems that require relatively high load power.
The device contains a built-in voltage clamp on
the outputs for inductive transient protection.
Power driver applications include relays, solenoids,
and other medium-current or high-voltage
loads.
The TPIC6B273 contains eight positive-edgetriggered
D-type flip-flops with a direct clear input.
Each flip-flop features an open-drain power
DMOS-transistor output.
When clear (CLR) is high, information at the D
inputs meeting the setup time requirements is
transferred to the DRAIN outputs on the positivegoing
edge of the clock (CLK) pulse. Clock
triggering occurs at a particular voltage level and
is not directly related to the transition time of the
positive-going pulse. When the clock input (CLK)
is at either the high or low level, the D input signal
has no effect at the output. An asynchronous CLR
is provided to turn all eight DMOS-transistor
outputs off. When data is low for a given output,
the DMOS-transistor output is off. When data is
high, the DMOS-transistor output has sink-current
capability.
Outputs are low-side, open-drain DMOS
transistors with output ratings of 50 V and 150-mA
continuous sink-current capability. Each output
provides a 500-mA typical current limit at
TC = 25°C. The current limit decreases as the
junction temperature increases for additional
device protection.
The TPIC6B273 is characterized for operation over the operating case temperature range of –40°C to 125°C.
