DESCRIPTION
The L9348 is a monolithic integrated quad low side
driver realized in advanced Multipower-BCD technol-
ogy. It is intended to drive inductive loads (relays,
electromagnetic valves) in automotive and industrial
applications.

note: parameters are not shown proportionally
time between two clamping periods is
