Why driver IC cost matters for your project
Choosing a driver IC is more than the unit price. For makers, students and procurement teams in South Africa the true cost includes lead time, shipping, VAT invoices and the risk of buying parts that don't meet system-level needs. Communica stocks a wide selection of driver ICs used for stepper and DC motor control, LED arrays and power-management gates-letting you compare real-world prices against immediate availability.
Value proposition: buy smarter, reduce downtime
Paying a little more for a local-ready part can save weeks on projects and exams. Our Samrand warehouse and branches in Pretoria and Cape Town let you collect same-day when in-stock, get VAT invoices for departmental purchasing, and obtain quotes for bulk buys.
How cost components break down
- Unit price - manufacturer/package variant and included features (current rating, gate drive, integrated MOSFETs).
- Availability & lead time - local stock vs special order; affects project schedules and assignments.
- Support & documentation - access to datasheets, reference designs and application notes for quick integration.
- Accessories - carrier PCBs, screw-terminal adapters, decoupling caps and MOSFETs that alter total build cost.
Popular categories and sample brands we stock
Common driver classes: H-bridge motor drivers (for brushed DC motors), stepper drivers (microstepping), LED drivers (constant current) and gate drivers (for power stages). Communica carries hundreds of brands spanning hobby favourites to industrial families.

Specification callouts to watch when comparing price
A cheaper IC may skip features that save downstream cost. When comparing, check:
- Continuous and peak current ratings and thermal limits.
- Supply voltage range and gate-drive voltages.
- Protection features: undervoltage lockout, overcurrent behaviour, and fault reporting.
- Package type - surface-mount vs through-hole affects prototyping cost.
Quick compatibility check (practical)
Match the driver IC's current rating to the motor's stall current with a safety margin (typically 1.2-1.5×). For LED drivers, size the constant-current rating to the total forward current of series/parallel strings. If unsure, bring the motor/LED spec to a branch: see branch hours and locations at driver ICs in stock.
