TLE9183QK
MOTIX™ TLE9183QK motor gate driver IC for 12 V brushless DC motor control and safety-relevant applications
The MOTIX™ TLE9183QK is an advanced gate driver IC dedicated to control 6 external N-channel MOSFETs forming an inverter for high current 3 phase motor drives application in the automotive sector. Three integrated current sense amplifiers for shunt signal conditioning are integrated. Thanks to the powerful driver stage with typ. 2 A output current per channel, the 3-phase gate driver is ideally suited for safety related applications. This device is developed according to ISO26262 ASIL-D workflow.
