• Manufacturer Part Number: A3986SLD-T
• Description: DUAL H-BRIDGE MOSFET DRVR W/MICRO TRANS
• Manufacturer: Allegro MicroSystems, Inc.

A3986
Description (continued)
The above-supply voltage required for the high-side N-channel
MOSFETs is provided by a bootstrap capacitor. Efficiency is
enhanced by using synchronous rectification and the power FETs
are protected from shoot-through by integrated crossover control
and programmable dead time.

In addition to crossover current control, internal circuit protection
provides thermal shutdown with hysteresis and undervoltage lockout.
Special power-up sequencing is not required.
This component is supplied in an 38-pin TSSOP (package LD). The
package is lead (Pb) free, with 100% matte tin leadframe plating.
