TLE9877QXW40XUMA1 integrated SoC
The TLE9877QXW40XUMA1 is a highly integrated System-on-Chip (SoC) from Infineon's MOTIX™ TLE987x family, designed specifically for automotive 3-phase Brushless DC (BLDC) motor control. This device integrates a 32-bit ARM Cortex-M3 core operating at up to 40 MHz with 64 KB of Flash memory and 6 KB of RAM. It features a fully integrated NFET gate driver with an embedded charge pump, allowing direct control of external power MOSFETs without requiring external bootstrap capacitors. The chip operates from a single supply voltage ranging from 5.5V to 28V and includes a LIN 2.2 transceiver, a high-speed operational amplifier for current sensing, and a 10-bit ADC. Housed in a compact 48-pin VQFN package (7x7mm), it is qualified for automotive Grade 0 applications, supporting a junction temperature range from -40°C to +175°C, making it robust enough for under-the-hood environments.
