The TLE 6220 GP is an quad-low-side power switch which provides a serial peripheral interface (SPI) to control the 4
power DMOS switches, as well as diagnostic feedback. The power
transistors are protected against short to VBB, overload,
overtemperature and against overvoltage by an active zener clamp. It can
be applied for purposes such robotic controls, switch for automotive and industrial system, solenoids, relays and resistive loads, injectors, and µC Compatible Power Switch for 12 V and 24 V Applications.
TLE 6220 GP (quad switch) if combine to TLE 6230 GP and TLE 6240
GP(16-fold switch) can be driven to a modern Engine
Management/Powertrain system. Combination among TLE 6230 GP with TLE
6240 GP (16-fold switch) results relays and general purpose loads and
with TLE 6220 GP (quad switch) can be driven to the injector valves.
It is protected by embedded protection functions and designed for
automotive and industrial applications. The paralel SPI configuration is
given in the engine management application diagram section. So we can see a Daisy Chain Application TLE 6220 GP in a brief description.
The TLE 6220 GP summarizes Vs=4.5-5.5 V, drain source voltage= 60 V, On Resistance= 0.32 ohm, and Output Current= 1-3 A.
