Product Overview
Sprague UDN2953B monolithic bipolar full-bridge motor driver IC for bidirectional control of DC or stepper motors using PWM. Provides a compact interface between low-power logic signals and higher-current motor loads.
Key Features
- Function: Full-bridge (H-bridge) PWM motor driver
- Package: 16-pin DIP (through-hole)
- Continuous output current: 2.0 A
- Peak output current: 3.5 A
- Maximum output voltage (motor supply): 50 V
- Logic supply (VCC): typically 4.5 V to 7 V
- Logic compatibility: TTL / 5 V CMOS
- Protection: thermal shutdown with hysteresis
- Protection: internal flyback (transient-suppression) diodes
Applications
- Bidirectional DC motor drive (forward/reverse/brake) with PWM speed control
- Legacy CNC and automation motion control repairs
- 2-phase stepper motor driver stages (verify system design/current)
Frequently Asked Questions
Is this the through-hole DIP version?
Yes. UDN2953B is the 16-pin DIP package version.
What are the current and voltage limits?
2.0 A continuous output current, 3.5 A peak output current, and up to 50 V motor supply/output voltage.
What logic levels can drive it?
Compatible with TTL and 5 V CMOS logic. Logic supply (VCC) is typically 4.5 V to 7 V.
Does it include protection features?
Yes. It includes thermal shutdown with hysteresis and internal flyback diodes for inductive loads.
