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.
