Overview

The Digilent PmodOC1 Open Collector Output

Module Board (the OC1™) can drive high

current devices using MMBT3904 output

transistors. The transistors are driven by logic

signals from a Digilent system board.

The transistors function as switches and can

drive relays and turn on LEDs, motors, and

other outside devices.

Features include:

•

four 100mA (200mA max) MMBT3904

transistors

a 6-pin header and 6-pin connector

four output clamp diodes

40V voltage threshold

small form factor (0.75” x 0.80”).

J1 Connector

GND

Vcc

Functional Description

Each transistor functions independently of the

others, so they can be used individually or

simultaneously.

Each transistor has a collector that conducts

current between an outside device and a

ground connection established by the OC1.

When a transistor is turned on, current flows

through the circuit connected to the

corresponding pin on J2.

The OC1 has four output clamp diodes that

prevent damage to the transistors by

dissipating fly-back current from inductive

loads.

The OC1 has a 6-pin header for easy

connection to a Digilent system board. Some

OC1 Circuit Diagram

system boards, like the Digilent Pegasus

board, have a 6-pin header that can connect to

the module with a 6-pin cable. To connect the

OC1 to other Digilent system boards, a Digilent

Modular Interface Board (MIB) and a 6-pin

cable may be needed. The MIB plugs into the

system board, and the cable connects the MIB

to the OC1.The OC1 also has a 6-pin

connector for easy connection to the Digilent

Pmod connector module.
