On 3776 chips and troubles with fried drivers.
On my stepper driver board using 3776, I found that the gate bypass diodes were essential to save the FET driver chips. The
Ericcson book suggested they were optional. I found they were essential. Without the diode bypasses on the gates, the Fets fried
in minutes. I lost several chips before sorting this glitch out.
