General description
The TLE6288 R is a 6-channel (150mΩ)
Smart Multichannel Switch in SPT4 Tech-
nology. The IC has embedded protection,
diagnosis and configurable functions.
Channel 1-3 are highside channels with
integrated charge pump and can be pro-
grammed individually to do autonomous
peak and hold current regulation with
PWM. Channel 4-6 (also with integrated
charge pump) can be configured to work
as highside Switch or lowside Switch. This
IC can be used to drive standard automo-
tive loads in highside or lowside applica-
tions with switching frequencies up to
10kHz. In addition the TLE6288R can be
used to drive autonomously up to 3 induc-
tive Peak&Hold (valves, coils) loads with
programmable peak and hold current val-
ues.
