3.3 V/15 A Electrical Specification
PKU 4510 PI
Tref = -30 to +110C, VI = 36 to 75 V, sense pins connected to output pins unless otherwise specified under Conditions.
Typical values given at: Tref = +25°C, VI= 53 V, max IO, unless otherwise specified under Conditions.
An external capacitor of 1 F is used on the input during all measurements.
