What this STSPIN L62 driver packs into the 32-VFQFPN
The STMicroelectronics L6226QTR is a fully integrated DMOS motor driver from the STSPIN L62 series, combining control logic and a power stage in a single 32-VFQFPN (5x5 mm) package. It drives one bipolar stepper motor or two brushed DC motors using four half-bridge outputs, each rated for 1.4 A continuous. The supply and load voltage range spans 8 V to 52 V. A parallel interface handles the control signals, and the DMOS output stage integrates the power FETs and recirculation diodes. This is a general-purpose part for board-level motion control.
Temperature grade — industrial floor, not automotive under-hood
The junction temperature range is -25°C to 125°C. That covers most factory-floor and indoor equipment, but the -25°C lower limit means it is not rated for cold-start automotive, outdoor telecom cabinets in freezing climates, or refrigeration environments. The 125°C upper end is fine for motor-drive applications where the driver sits near the motor and sees some self-heating.
Lifecycle and sourcing — active, no LTB clock ticking
The L6226QTR carries an active lifecycle status and ROHS3 compliance. That means STMicroelectronics is still manufacturing it, there is no last-time-buy notice, and it is fit for new designs.
