LTC4446 is used as a driver for high-side and low-side outputs. Load is inductive (200uH), Vin=60V, Vcc=12V.

LTC4446 fails to operate after several hours. The symptoms are, in a case, excessive current through Vcc (12V), and in other case excessive current through the Tinp and/or Binp digital inputs.
