Frequently Asked Questions
How many integrated circuits are included with this order?
Each purchase is for one Unitrode UC3622V integrated circuit.
What package format does this device use?
It uses the Unitrode 'V' package style, which is a 15-lead vertical power SIP with staggered pin spacing and a metal mounting tab.
Why purchase this individual driver IC instead of hunting down a bulk surplus lot?
