ULN2003V12, ULN2003F12

Multi-Channel Relay and Inductive Load Sink Driver

Description

Pin Assignments

( Top View )

The ULN2003V12 and ULN2003F12 are multi-channel sink drivers

comprised of 7-channel and 4-channel output stages respectively.

The ULN2003V12 sink driver features 7 low output impedance drivers

that minimize on-chip power dissipation and an actual low power

upgrade version for popular ULN2003A family in real applications.

When driving a typical 12V relay coil, a ULN2003V12 will dissipate 12

times lower power compared to ULN2003A. ULN2003F12 is a lower

power variant benefiting from fewer channel integration and a better

fit for applications requiring only 4-channel drivers, such as driving

low voltage stepping motors, etc.

The ULN2003V12 and ULN2003F12 both support 3.3V to 5V CMOS

logic input interface, thus making it compatible to a wide range of

micro-controllers and other logic interfaces, and also feature an

improved input interface that minimizes the input DC current drawn

from the external drivers. The input RC snubber circuit integrated at

ULN2003V12 and ULN2003F12 improves the performance in noisy

operating conditions, and the internal pull-down resistor at input stage

helps allow input logic to be tri-stated.

As shown in the Functional Diagram, each output of the ULN2003V12

and ULN2003F12 features an internal free-wheeling diode connected

in a common-cathode configuration at the COM pin which provides

flexibility of increasing current sink capability through combining

several adjacent channels in parallel. Under typical conditions the

ULN2003V12 can support up to 1.0A of load current when all 7-

channels are connected in parallel.
