Stories and What We Learn

Story 1:

A technician was troubleshooting a circuit that was not working properly. He noticed that the UDN2916B-T was getting very hot. He checked the datasheet and realized that he had exceeded the maximum power dissipation. He replaced the UDN2916B-T with a larger heat sink and the circuit worked properly.

What we learn: It is important to check the datasheet for the maximum power dissipation of a device before using it in a circuit.

Story 2:

A student was building a robot that used the UDN2916B-T to drive the motors. He connected the output pins of the UDN2916B-T directly to ground. This caused the device to latch up and the robot stopped working. He rewired the circuit so that the output pins were not connected to ground and the robot worked properly.

What we learn: It is important to not connect the output pins of the UDN2916B-T to ground.

Story 3:

An engineer was designing a circuit that used the UDN2916B-T to drive a solenoid. He did not use a flyback diode across the solenoid. When the solenoid was turned off, the voltage spiked and damaged the UDN2916B-T. He added a flyback diode to the circuit and the UDN2916B-T worked properly.

What we learn: It is important to use a flyback diode across inductive loads when using the UDN2916B-T.
