TLE 6208-3 G
Every driver block from DRV 1 to 3 contains a low-side driver and a high-side driver. Both
drivers are connected internally to form a half-bridge at the output. This reduction of
output pins was necessary to meet the small P-DSO-14 package.
When commutating inductive loads, the dissipated power peak can be significantly
reduced by activating the transistor located parallel to the internal freewheeling diode. A
special, integrated “timer” for power ON/OFF times ensures that there is no crossover
current.
