description

The TPIC2406 is a monolithic, high-voltage,

high-current, quadruple power driver designed for

use in systems that require high load power. The

device contains built-in high-speed output clamp

diodes for inductive transient protection. Power

driver

applications

include

lamps,

relays,

solenoids, and dc stepping motors.

The device features four inverting open-drain outputs, each controlled by an input storage latch with common

clear and enable controls. All inputs accept standard TTL- and CMOS-logic levels. The CLR function is

asynchronous and turns all four outputs off regardless of data inputs. Taking ENBL low puts the input latch into

a transparent mode, allowing the data inputs to affect the output. In this state, all four outputs are held off while

CLR is low, but return to the stages on the data inputs when CLR goes high. When ENBL is taken high, the latch

is put into a storage mode and the last state of the data inputs is held in the latches. If CLR is taken low, the data

in the latches is cleared and all outputs are turned off. If CLR is taken high again, ENBL must be cycled low to

read new data into the latch.
