General Description
The TLE6288R is a 6-channel (150 mΩ) Smart Multichannel Switch in Smart Power Technology. The IC has
embedded protection, diagnosis and configurable functions. Channels 1-3 are highside channels with integrated
charge pump and can be programmed 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 automotive loads in highside or lowside applications with switching
frequencies up to 10 kHz. In addition the TLE6288R can be used to drive autonomously up to 3 inductive
peak & hold (valves, coils) loads with programmable peak and hold current values.
