36 V output rating
2.4 A, DC motor driver
Synchronous rectification
Internal undervoltage lockout (UVLO)
Thermal shutdown circuitry
Crossover-current protection
Very thin profile QFN package
The A3995 is designed to drive two DC motors at currents up to
2.4 A. Capable of drive voltages up to 36 V, the A3995 includes
two independent fixed off-time PWM current regulators that
operate in either fast or slow decay mode, as determined by
the MODE input. Internal synchronous rectification control
circuitry is provided to improve power dissipation during
PWM operation.
Protection features include: thermal shutdown with hysteresis,
undervoltage lockout (UVLO) and crossover current protection.
Special power-up sequencing is not required.
The A3995 is supplied in a 36 pin QFN package (suffix EV)
with exposed power tab for enhanced thermal performance. It
Package: 36 pin QFN
0.90 mm nominal height (suffix EV)
has a 6 mm × 6 mm footprint, with a nominal overall package
height of 0.90 mm, and is lead (Pb) free, with 100% matte tin
leadframe plating.
