Capable of drive voltages up to 36 V, the A3995 includes Synchronous rectification two independent fixed off-time PWM current regulators that Internal undervoltage lockout (UVLO) operate in either fast or slow decay mode, as determined by Thermal shutdown circuitry the MODE input. Internal synchronous rectification control Crossover-current protection circuitry is provided to improve power dissipation during Very thin profile QFN package 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 has a 6 mm 6 mm footprint, with a nominal overall package PACKAGE: height of 0.90 mm, and is lead (Pb) free, with 100% matte tin leadframe plating. 36-pin QFN 0.90 mm nominal height (suffix EV) Not to scale Typical Application Diagram CP1 CP2 VCP VBB VBB VDD OUT1A OUT1A OUT1B MODE1 OUT1B A3995 PHASE1 SENSE1 ENABLE1 Microcontroller or SENSE1 Controller Logic VREF1 MODE2 PHASE2 OUT2A OUT2A ENABLE2 VREF2 OUT2B OUT2B SENSE2 SENSE2 A3995DS Rev. 3 September 10, 2018 MCO-0000501 GND GND GND GND
