Driver ICs supplier: local availability and real-world value
When a stepper motor jumps, an LED array flickers, or a MOSFET thermal limit bites your prototype, having the right driver IC on the shelf changes a multi-day delay into a same-week fix. Communica is one of the region's largest distributors of semiconductors and driver ICs, stocking popular motor drivers, LED drivers, gate drivers and MOSFET drivers that South African makers, students and engineering teams use every day. Benefit from local stock, branch collection in Samrand or Cape Town, VAT invoicing for institutions and fast quotes for procurement.
Why buy driver ICs locally?
- Availability: avoid long lead times from offshore suppliers when deadlines are tight.
- Support: hands-on advice from staff familiar with local projects and education kits.
- Procurement-friendly: institution-ready VAT invoices and account quoting for bulk buys.
Common driver types we stock
Driver IC choice depends on load type and control interface. Typical families covered: stepper motor drivers (microstepping), brushed/DC motor drivers (H-bridges), BLDC/PWM drivers, LED current drivers (constant current), gate drivers for high-side/low-side MOSFET control, and specialised sensor interface drivers. For hands-on browsing see our Shop by Category and the full All Products index.
Quick spec comparison
Use the table below to match driver families to common project needs.
| Driver Family | Typical Voltage | Control | Best for |
|---|---|---|---|
| Stepper microstepping | 8-48V | Step/Dir / SPI | 3D printers, CNC, precise position |
| H-bridge DC drivers | 5-36V | PWM / Direction | Robotics, conveyors |
| BLDC drivers | 12-60V | FOC / Commutation | Brushless motors, drones |
| LED current drivers | up to 60V | I2C / PWM | Signage, LED arrays |
Selection checklist - what to verify before ordering
- Voltage and current headroom: choose a driver rated 20-30% above expected peaks.
- Control interface compatibility: MCU PWM, Step/Dir, I2C or SPI must match your board.
- Thermal strategy: package power dissipation, heatsinking or PCB copper area.
- Protection needs: short-circuit, over-temperature and current limiting features.
- Availability and lead times: confirm stock with branch collection options in Branches & Trading Hours.
Practical wiring example (bipolar stepper)
Typical wiring for a bipolar stepper using a stepper driver IC or module:
MCU ----> STEP, DIR pins Driver VCC ----> 12-24V supply Motor A+ A- B+ B- connected to driver outputs GND common between MCU and driver
Remember: set current limits on the driver before connecting the motor to avoid overcurrent events - consult the driver datasheet for the adjustment method (pot or register).
If you need help matching a driver to a motor, our technical team can walk through calculations and suggest accessory bundles such as decoupling capacitors, TVS diodes and breakout modules. Learn more about Communica on our About Us page.
