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.
