AN41908A-VB Equivalent & Substitute Parts

Part Overview

The AN41908A-VB is a bipolar motor driver IC manufactured by Panasonic Electronic Components, designed for integrated motor control applications. This device integrates both control and power stages in a 44-QFN package, supporting stepper and brushed DC motor operation across a 2.7V to 5.5V supply range. The part is currently obsolete, making equivalent and substitute components necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AN41908A-VB is determined by the following critical parameters:

Motor driver functionality requires matching of motor type support (bipolar stepper and brushed DC), fully integrated control and power stage architecture, and half-bridge output configuration. The serial interface, power MOSFET technology, and step resolution range (1 ~ 1/256) define the control capability set.

Electrical compatibility is established through matching supply voltage range (2.7V ~ 5.5V), load voltage range (2.7V ~ 5.5V), and output current specifications (250mA, 150mA). Operating temperature range (-20°C ~ 125°C) must be maintained.

Physical compatibility requires identical or functionally equivalent 44-QFN package specification with surface mount mounting type. Compliance certifications (RoHS Compliant) and moisture sensitivity level (MSL 3) establish reliability and handling requirements.

Parameter Comparison

Engineering Selection Recommendations

The KA41908A-VB from Nuvoton Technology Corporation is listed as an alternative part number. However, complete electrical and mechanical parameter specifications for the KA41908A-VB are not provided in the available data. Direct substitution cannot be confirmed without verification of matching motor type support, output configuration, interface type, current ratings, voltage specifications, temperature range, and package dimensions.

The AN41908A-VB maintains RoHS Compliance status. The KA41908A-VB is listed as REACH Unaffected, indicating different regulatory classification. Selection between these parts requires confirmation that all critical parameters align with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the KA41908A-VB directly replace the AN41908A-VB?

A: Direct substitution cannot be confirmed based on available data. The KA41908A-VB specifications for motor type support, output configuration, current ratings, voltage ranges, and package dimensions must be verified against the AN41908A-VB requirements before implementation.

Q: What parameters are critical for motor driver substitution?

A: Motor type support (bipolar stepper and brushed DC), output configuration (half bridge), interface type (serial), current ratings (250mA, 150mA), supply voltage range (2.7V ~ 5.5V), load voltage range (2.7V ~ 5.5V), operating temperature range (-20°C ~ 125°C), and package specification (44-QFN) must match or exceed the original part specifications.

Q: Does the 44-QFN package specification apply to both parts?

A: The AN41908A-VB uses a 44-VFQFN package. Package specifications for the KA41908A-VB are not provided in the available data and must be confirmed.

Q: What is the significance of the obsolete product status?

A: The AN41908A-VB is obsolete, meaning it is no longer manufactured by Panasonic. Substitute parts with active product status, such as the KA41908A-VB, may be necessary for ongoing system support and new designs.

Q: Are there compliance differences between these parts?

A: The AN41908A-VB is RoHS Compliant with MSL 3 (168 Hours) moisture sensitivity. The KA41908A-VB is listed as REACH Unaffected. Compliance requirements for your application must be verified against these designations.
