Description (continued)
3-Phase Brushless DC Motor Pre-Driver
Internal circuit protection includes thermal shutdown with hysteresis,
undervoltage lockout, and dead time protection. Special power-up
sequencing is not required. Operating temperature range is –20°C
to 105°C.
Selection Guide
The device package is a 32-contact, 5 mm × 5 mm, 0.90 mm
nominal overall height QFN, with exposed pad for enhanced thermal
dissipation. This small-footprint package is lead (Pb) free, with 100%
matte tin leadframe plating.
