Electrical Characteristics
This section describes the electrical characteristics of the PD70101/PD70201 device.
The following specifications apply over the operating ambient temperature of –40 °C ≤ TA ≤ 85 °C (except where
otherwise noted with VPP = 48 V; VEN = HIGH, FFREQ = 250 kHz). Production tests were performed at 25 °C. Unless
otherwise specified, VPP is with respect to VPN_IN and VCC is with respect to PGND.
