Key Parameters

Substitute Part Grouping Explanation

Substitution for the AH5773-MP-13 is determined by strict alignment of the following critical parameters:

• Function: Fully integrated driver with control and power stage
• Motor Application: Brushless DC (BLDC) motor control
• Output Configuration: Half Bridge topology (2 outputs)
• Interface Protocol: PWM control
• Power Delivery: 1A output current capability
• Supply Voltage Range: 2.4V to 18V operation
• Load Voltage Range: 2.4V to 18V
• Package Form Factor: 8-pin MSOP with exposed pad
• Temperature Rating: -40°C to 150°C junction temperature
• Compliance: ROHS3 and REACH requirements

Substitute parts must match all electrical specifications, package dimensions, and pin configuration to ensure direct replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The AH5773-MP-13 maintains Last Time Buy status, making supply continuity a critical consideration for ongoing production. The part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection of equivalent parts must prioritize identical electrical specifications, package geometry, and thermal characteristics to ensure functional compatibility without circuit modification.

The 8-MSOP package with exposed pad provides optimal thermal dissipation for the 1A output stage. Surface mount mounting type is standard for modern PCB assembly processes. The extended operating temperature range of -40°C to 150°C supports applications across industrial and automotive environments.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the AH5773-MP-13?

A: A valid substitute must match all electrical parameters including 1A output current, 2.4V to 18V supply and load voltage ranges, half-bridge output configuration, PWM interface, and -40°C to 150°C operating temperature. The package must be 8-MSOP with exposed pad, and compliance certifications (ROHS3, REACH) must be maintained.

Q: Can I use a different package variant of the AH5773?

A: Package substitution is not permitted. The 8-MSOP with exposed pad is specified for thermal and electrical performance. Alternative packages may have different pin assignments, thermal characteristics, or board layout requirements that would necessitate circuit redesign.

Q: Is the AH5773-MP-13 suitable for high-temperature applications?

A: The device operates to 150°C junction temperature, supporting extended temperature range applications. Thermal management through proper PCB layout and the exposed pad design ensures reliable operation within this range.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy indicates this part number will not be manufactured beyond a specified date. Design teams should evaluate long-term supply requirements and consider equivalent alternatives from the same or other manufacturers to ensure production continuity.

Q: Are there cross-manufacturer equivalents available?

A: Equivalent parts from other manufacturers must match all specified electrical and mechanical parameters. Substitution decisions should be based on parametric alignment rather than manufacturer preference.
