I think you may be looking for Cyborg 2: Glass Shadow.
In the year 2074 the PinWheel corporation creates an 'almost-human' cyborg Casella Reese, aka Cash, designed specifically to charm/seduce her way into a rival manufacturer's headquarters and then self-detonate. Things go awry, when she starts to have feelings for a human Colton Ricks, aka Colt 45, who works for PinWheel as a martial arts instructor. He falls for Cash as well, and with the help of Mercy, they escape. PinWheel Corp. sends Danny Bench, a 'Cyborg Tracker' after both Colt and Cash. Violence ensues.
It was following by a sequel, Cyborg 3: the Recycler
Prepare yourself for the all too deadly future. Cash, the heroine of Cyborg 2, is living safe in the free zone. But not for long. Biomechanical problems are taking down her systems and a visit to a doctor in Silica confirms her worst fears. She is more then a marvel of cyborg technology. She is the first of her kind to become a creator-she is pregnant.
What does not match, as you might guess from that she shows up in the sequel, is that Cash does not die after exiting the facility, although in Cyborg 3, the scene where Evans shows Cash is pregnant does have him holding what looks like a remote control, plugged into her.
