Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMIS30623C6238RG is determined by the following critical parameters:

Motor driver type and stepper motor compatibility (bipolar configuration required), fully integrated control and power stage architecture, half-bridge output configuration (4 outputs), step resolution support (1/2, 1/4, 1/8, 1/16), voltage supply range compatibility (minimum 6.5V to 29V), output current capability (570mA or greater), and operating temperature range (-40°C to 165°C or equivalent).

The NCV70627DQ002AR2G qualifies as a substitute based on matching motor type (bipolar stepper), integrated driver architecture, half-bridge output configuration, identical step resolution support, overlapping voltage supply range (5.5V ~ 29V), and compatible operating temperature range (-40°C ~ 160°C). Interface differences (LIN versus Serial) and package variations (20-SOIC versus 36-SSOP-EP) represent design trade-offs that must be evaluated within specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

The AMIS30623C6238RG is classified as obsolete, necessitating evaluation of active alternatives for new designs and ongoing production support. The NCV70627DQ002AR2G is an active product from the same manufacturer, offering functional equivalence in motor driver architecture, output configuration, and step resolution capability.

Both devices maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and handling consistency. The NCV70627DQ002AR2G extends supply voltage compatibility to 5.5V (versus 6.5V minimum for the AMIS30623C6238RG) and operates within a 5°C lower maximum junction temperature range (-40°C to 160°C).

Package differences (20-SOIC versus 36-SSOP-EP) and interface architecture (LIN versus Serial) require PCB layout and firmware modifications. The NCV70627DQ002AR2G includes an exposed pad for enhanced thermal management, beneficial in high-current applications.

Frequently Asked Questions (FAQ)

Q: Can the NCV70627DQ002AR2G directly replace the AMIS30623C6238RG without PCB modifications?

A: No. The devices use different package types (20-SOIC versus 36-SSOP-EP) and interface protocols (LIN versus Serial), requiring PCB redesign and firmware updates.

Q: What is the significance of the lower minimum supply voltage (5.5V) in the NCV70627DQ002AR2G?

A: The NCV70627DQ002AR2G supports operation at 5.5V, extending compatibility to lower-voltage applications. Systems designed for the AMIS30623C6238RG minimum of 6.5V remain compatible with the substitute.

Q: Does the 5°C difference in maximum operating temperature affect substitution suitability?

A: The NCV70627DQ002AR2G maximum junction temperature of 160°C versus 165°C for the AMIS30623C6238RG represents a minor constraint. Applications operating below 160°C encounter no thermal limitations.

Q: Why does the NCV70627DQ002AR2G have more pins (36 versus 20)?

A: The 36-SSOP-EP package accommodates additional functionality, including an exposed thermal pad for improved heat dissipation in power-intensive applications.

Q: Are both devices suitable for automotive applications?

A: The NCV70627DQ002AR2G carries automotive grade designation. The AMIS30623C6238RG does not specify automotive qualification in the provided parameters.
