DS3686 Dual Positive Voltage Relay Driver

General Description

The DS3686 is a high voltage/current positive voltage relay

driver having many features not available in present relay

drivers.

levelsÐbase drive for the output transistor is obtained from

the load in proportion to the required loading conditions.

Typical V

power with both outputs ‘‘ON’’ is 90 mW.

The circuit also features output transistor protection if the

supply is lost by forcing the output into the high imped-

PNP inputs provide both TTL/LS compatibility and high in-

put impedance for low input loading.

ance ‘‘OFF’’ state with the same breakdown levels as when

was applied.

Output leakage is specified over temperature at an output

voltage of 54V. Minimum output breakdown (ac/latch break-

down) is specified over temperature at 5 mA. This clearly

defines the actual breakdown of the device since the circuit

has incorporated in it an internal reference which does not

allow output breakdown latching found in existing relay driv-

ers. Additionally, this internal reference circuit feature will

eliminate the need in most cases of an external clamping

(inductive transient voltage protection) diode. When the out-

put is turned ‘‘OFF’’ by input logic conditions the resulting

inductive voltage transient seen at the output is detected by

an internal zener reference. The reference then momentari-

ly activates the output transistor long enough so that the

relay energy is discharged. This feature eliminates the need

of external circuit protection components and insures output

transistor protection.
