TMC32NP-MLP, TMC32NP2-SM8

Description
The TMC32NP-MLP is a miniature N & P channel MOSFET complementary pair, ideally suited for motor drive applications. It perfectly complements the TMC239A-LA / TMC249A-LA stepper motor drivers, in order to build a 2A (4 devices) / 4A (8 devices) stepper motor driver the size of a stamp.
The TMC32NP2-SM8 is a miniature N & P channel MOSFET full bridge, ideally suited for motor drive applications. It perfectly complements the TMC239A-SA / TMC249A-SA stepper motor drivers, in order to build a 1.5A / 2.5A peak current capability (5 seconds) stepper motor driver on a two layer PCB. Using just one small fullbridge, a DC motor can be operated in four quadrant mode.
