Unless otherwise specified, the following specifications apply over the operating ambient temperature of -40

°C ≤ TA ≤ 85°C except where otherwise

noted with the following test conditions: VPP= 48V; VEN = HIGH, fs = 250 kHz. Production tests performed at 25°C. Unless otherwise specified VPP is

with respect to VPN_IN, VCC is with respect to PGND.
