4988 Driver Features

• Low RDS (on) output

• Automatic current decay mode detection/selection

• Mixed and slow current decay mode

• Low power dissipation synchronous rectification

• Internal UVLO

• Cross current protection

• 3.3 and 5 V compatible logic power supplies

• Thermal shutdown circuit

• Ground short circuit protection

• Load short circuit protection

• Five optional step modes: Full, 1/2, 1/4, 1/8 and 1/16

DRV8825 Driver Features

• The maximum current is 2.5A.

• the highest support for 32 subdivisions.

• 4 layer PCB board, better heat dissipation performance.

• the chip internal resistance is smaller, lower heat, better heat dissipation.

• Size: 1.5mmX2mm (same as 4988)

• Driven current: 2.5A

• Subdivision: 1, 1/2, 1/4, 1/8, 1/16, 1/32

• Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield, more stable performance

Offline appearance update: acrylic shell is transparent, buttons are red and yellow.
