MIC4807BN

Overview

The MIC4807BN is an 80V, 8-channel addressable low-side driver IC manufactured by Microchip Technology. It features non-inverting logic inputs compatible with TTL and CMOS standards. The device utilizes a comparator-based input structure for each channel. It is housed in an 18-pin DIP package with a 0.300-inch (7.62mm) width. This component serves as a gate driver for power switching applications requiring multiple independent control lines.

Feature Summary

• Eight independent addressable output channels
• TTL and CMOS compatible logic inputs
• Non-inverting signal configuration
• Integrated latch functionality

Applications

• Multi-channel power switching systems
• Industrial motor control interfaces
• High-voltage load driving circuits
• Addressable LED matrix drivers

Procurement Notes

Verify the manufacturer origin carefully, as the part was originally developed by Micrel before its acquisition by Microchip Technology. Confirm the specific package variant matches the 18-DIP requirement. Check current availability status as older revisions may be marked obsolete or limited stock. Ensure the datasheet version aligns with the required electrical specifications for your design.

Selection Notes

Select this component when designing circuits that require isolated control of eight distinct low-side loads. It is suitable for environments where TTL or CMOS logic levels interface directly with higher voltage power stages. Consider the thermal performance of the DIP package if high continuous currents are expected. Verify that the 80V rating exceeds the maximum voltage present on the driven loads.

Part Context

This device belongs to the MIC4807 series of addressable low-side drivers. It shares functional similarities with other multi-channel drivers but is distinguished by its specific 8-channel architecture and 80V rating. The transition from Micrel to Microchip Technology maintains the part number continuity while updating manufacturing sources.

Replacement Considerations

Direct substitutes include other 8-channel addressable low-side drivers with similar voltage ratings. Verify pin compatibility and logic input thresholds before swapping. Generic replacements may lack the specific latch features or addressability of the original design.
