• Manufacturer Part Number: zxct1032
• Description: Zxct1032 - High-side Inrush And Current Limit Controller
• Manufacturer: Zetex Semiconductors plc.

Absolute maximum ratings
V
Voltage on any pin relative to GND ............................................................. -0.6V and V
Maximum differential voltage between V
Junction temperature range ........................................................................ -40 to 150°C
Storage temperature range .......................................................................... -55 to 150°C
Operation above the absolute maximum rating may cause device failure. Operation at the
absolute maximum ratings, for extended periods, may reduce device reliability.
