(PDF) AN6651 Datasheet download
This is probably a Part 1 since this is an ongoing project, but I am working occasionally but steadily on a ‘Tron overhaul for an HvZ player at a nearby campus.
Could it have something to do with dropout voltage?
As it turns out, “voltage regulator” is a very close guess. Posted by torukmakto4 at 7: Surely if the stock setup demanded a lower ROF than the direct-driven motor would produce and no colder-wound motor was available, you could do well enough with a dumb, cheap, string of diodes – or even a generic voltage regulator.
Saturday, October 19, Nitron A6n651 Observations. This is why throwing higher voltage batteries at a stock ‘tron makes the flywheel rev higher, but doesn’t change the terrible ROF.
One is that the pusher is cycle-controlled with the switch mounted on top of the battery box that follows the stepped edge of the cam disk but there is no active braking.

More or less a fancy linear voltage regulator that allows taking into account the motor IR and Kv in the selection of 2 external resistor values to get a very stable constant-speed, governor-like behavior.
Newer Post Older Post Home. Except it makes sense in combination with the next bit, which makes AB difficult to implement in the stock configuration.
Pages Home Chrono Data Archive. Haven’t checked, not worth the time to investigate the numbers of this application. Along the way I came across 2 odd details about the stock Nitron electrical system.
Could there possibly be a need for that tight of speed control of this motor? This strange heatsinked 4-pin package hanging off the side of the PCB is the first thing many people notice about the stock motor setup on the ‘Tron pusher.

Peak current handling is 1. So why was this component used to drive the Nitron pusher motor?
That is the biggest mystery of them all. A quick Google nails it down what the mystery component is: Applications listed in the datasheet include tape decks and CD players.
At least people are aware you dataxheet to remove this PCB to do anything useful. Speculation has included that the device is a dtaasheet regulator or a MOSFET used for solid-state switching of the motor power with the small switches scattered all over the Nitron’s guts for various interlock purposes.
