Frequently Asked Questions
What are the maximum voltage and current ratings for each channel of the ULQ2802A?
Each of the 8 Darlington channels in the ULQ2802A is rated for a maximum collector voltage of 50 V and a maximum continuous output current of 500 mA, making it suitable for driving medium-power inductive loads such as relays and solenoids.
How does the ULQ2802A protect against inductive kickback when driving relay coils?
The ULQ2802A includes built-in transient suppression diodes on each of its 8 output channels. These clamp inductive kickback voltages below 50 V, protecting the driver and upstream logic from voltage spikes generated when relay or solenoid coils are de-energized.
Which logic families are compatible with the ULQ2802A input stage?
The ULQ2802A input resistors are sized for compatibility with TTL, CMOS, and PMOS logic outputs operating from a 5 V supply. The Darlington input stage provides sufficient base current at standard logic high levels, so no external series resistors are needed in most 5 V designs.
