Integrated diagnostics provide indication of undervoltage,
overtemperature, and power bridge faults. They can be configured
to protect the power FETs under most short circuit conditions.
Detailed diagnostics are available as a serial data word.
TheA4935 is supplied in a 48-pin LQFP with exposed thermal pad,
(suffix JP). This is a small footprint (81 mm2) power package. It is
lead (Pb) free with 100% matte tin leadframe plating.
