STPIC6C595M

Overview

The STPIC6C595M is a monolithic, medium-voltage, low-current power 8-bit shift register designed for moderate load power applications such as LEDs. It features an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register with separate clock inputs. The device includes built-in voltage clamping on outputs for inductive transient protection and supports cascading via a serial output port. It operates within a supply voltage range of 4.5 V to 5.5 V and functions across a temperature range of -40 °C to 125 °C.

Feature Summary

• Eight 100 mA DMOS outputs with low R DS(on)
• Built-in voltage clamp for inductive transient protection
• Cascadable architecture with serial output capability
• High ESD protection ratings

Applications

• LED driver systems
• Relay control circuits
• Solenoid actuation
• Low-current or medium-voltage load driving

Procurement Notes

Verify the specific suffix 'M' against official STMicroelectronics documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the exact electrical characteristics and industrial grade requirements. Confirm RoHS compliance status and packaging details directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component for applications requiring moderate load power with integrated inductive protection. Consider the 33 V output clamp and 100 mA continuous sink current when designing LED or relay interfaces. Evaluate thermal performance at higher junction temperatures due to current limit reduction. Ensure system voltage remains within the 4.5 V to 5.5 V operating range.

Part Context

This device belongs to the STPIC series of power logic shift registers. It combines standard shift register functionality with power driver capabilities, integrating DMOS transistors directly onto the silicon die. This integration simplifies design by reducing external component count while providing robust protection features suitable for automotive and industrial environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the STPIC family. Verify that any substitute maintains the same 8-bit configuration, voltage ratings, and current capabilities. Ensure the replacement device offers equivalent inductive transient protection and ESD ratings.
