Tailor-made for automotive motor management, the TLE9140EQW gate driver from Infineon eases the migration of methods from 12 V to 24 V or 48 V. The IC drives three-phase bridges for brushless DC motors generally present in automotive purposes, reminiscent of engine cooling followers, water pumps, oil pumps, and HVAC modules.
A part of the MOTIX household of motor management options, the TLE9140EQW gate driver might be paired with Infineon’s MOTIX TLE987x and TLE989x 32-bit motor management MCUs. The driving force accommodates a large enter voltage vary of 8 Vsm to 72 Vsm and affords high-voltage robustness as much as 110 V. It additionally supplies a gate driving functionality of ~230 nC/MOSFET as much as 20 kHz.
The TLE9140EQW is compliant with the ISO 26262 ASIL B useful security normal and operates over a temperature vary of -40° to +175°C. Safety and diagnostic features embrace overvoltage, undervoltage, cross-current, and overtemperature, together with drain-source monitoring and off-state diagnostics.
The TLE9140EQW gate driver is accessible now in small TS-DSO-32 packages. Infineon additionally affords an analysis board to hurry prototyping and ease the design-in course of.
