Overview
The ULN2003V12S16-13 is a multi-channel sink driver manufactured by Diodes Incorporated, packaged in a 16-pin SOIC. It features seven low output impedance drivers designed to minimize on-chip power dissipation compared to the ULN2003A family. The device supports 3.3V and 5.0V CMOS logic input interfaces and includes an internal RC snubber circuit for improved performance in noisy environments. Each channel provides an internal free-wheeling diode connected to a common cathode pin (COM), allowing parallel connection of channels to increase current sink capability up to 1.0A under typical conditions.
Feature Summary
- Features seven high-current sink drivers with low output impedance to reduce power dissipation.
- Includes integrated free-wheeling diodes at a common cathode pin for inductive kick-back protection.
- Supports 3.3V and 5.0V micro-controller logic interfaces with minimized input DC current.
- Incorporates an input RC snubber circuit to eliminate spurious operation in noisy environments.
Applications
- Relay Driver Applications
- Stepping Motor Applications
- Logic Level Shifter
Procurement Notes
Verify the specific package type and suffix against official Diodes Incorporated documentation before procurement. Confirm that the component meets RoHS compliance requirements and check for any automotive qualification status if required for the target application. Ensure the ordering information matches the exact part number variant needed for the design.
Selection Notes
Select this component when designing circuits requiring multiple low-side switches compatible with standard 3.3V or 5V logic levels. Consider its lower power dissipation characteristics relative to legacy ULN2003A devices. Evaluate the thermal resistance and power dissipation limits based on the expected load current and ambient temperature conditions during operation.
Part Context
This component belongs to the ULN2003V12 and ULN2003F12 series from Diodes Incorporated. It serves as a modern replacement option for older high-power darlington arrays, offering improved efficiency and noise immunity. The series is available in various packages including SOIC, TSSOP, and DFN to suit different PCB layout constraints.
Replacement Considerations
Consult Diodes Incorporated directly for recommended substitutes or updated product lines, as the datasheet explicitly states these parts are not recommended for new designs.
