Overview
The MIC2981/82YN is a high-voltage, high-current source driver array manufactured by Microchip Technology. It features an 18-pin PDIP package designed for through-hole mounting. The device supports a supply voltage range from 5V to 50V and delivers an output current of up to 350mA or 500mA depending on the specific variant configuration. It operates within a temperature range of -40°C to 85°C. The component is engineered to interface directly with logic-level TTL, CMOS, or PMOS control signals, making it suitable for driving high-power loads.
Feature Summary
- High-voltage and high-current source driver architecture
- Direct compatibility with logic-level TTL, CMOS, and PMOS inputs
- Robust design for switching high-power inductive loads
Applications
- Driving high-power inductive loads
- Industrial control systems requiring high-side switching
- Automotive applications compatible with standard logic interfaces
Procurement Notes
Verify the exact suffix and revision code against the manufacturer's latest datasheet to ensure pinout and electrical specifications match your design requirements. Confirm that the 18-pin PDIP package aligns with your PCB footprint constraints. Check for any specific handling instructions related to electrostatic discharge during installation.
Selection Notes
Select this component when a high-side driver capable of handling significant current and voltage is required. Ensure the input logic levels of your controller are compatible with the specified TTL or CMOS thresholds. Consider thermal management solutions if operating near the maximum current limits or ambient temperatures.
Part Context
This part belongs to the MIC2981 series of peripheral source drivers. It serves as a replacement for legacy components like the UDN2981. The device integrates protection features typical of high-side driver arrays, providing a reliable interface between low-power logic circuits and high-power external loads.
Replacement Considerations
Publicly confirmed substitute part numbers include the UDN2981. Verify functional equivalence regarding pinout and electrical ratings before substitution.
