ABSOLUTE MAXIMUM RATINGS

Notes:

1. The duration of the 60V voltage must be limited to 1 second if current is drained from the Vout regulator. Supply voltage in steady state

must be limi ted to ensure that dissipation rating is not exceeded.

2. The magnitude of input and output voltages must never exceed Vbatt+0.3V or 60V, whichever is less, except for H1 and H2: Vbatt+15V

or 60V, whichever is less.
