TSC428EPA Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The TSC428EPA is a low-side gate driver IC manufactured by Analog Devices Inc./Maxim Integrated, designed to drive N-Channel and P-Channel MOSFETs with independent dual-channel configuration. This component operates as an inverting and non-inverting gate driver with a supply voltage range of 4.5V to 18V and peak output current capability of 1.5A for both source and sink operations.

The TSC428EPA is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system design, maintenance, and production continuity. Substitute parts must maintain compatibility across critical electrical parameters including supply voltage, logic voltage thresholds, output current ratings, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSC428EPA is determined by strict alignment with the following critical parameters:

Mandatory Compatibility Criteria:

• Driven configuration must remain low-side
• Channel type must be independent dual-channel
• Package form factor must be 8-DIP (0.300", 7.62mm)
• Input type must support both inverting and non-inverting operation
• Gate type must support N-Channel and P-Channel MOSFET operation

Allowable Parameter Variations: Substitute parts may exceed the original specifications in the following areas without compromising compatibility:

• Supply voltage range (may be wider than 4.5V ~ 18V)
• Logic voltage thresholds (may accommodate higher VIH levels)
• Peak output current (may exceed 1.5A source/sink rating)
• Rise/fall time performance (faster switching is acceptable)
• Operating temperature range (may extend beyond -40°C ~ 85°C)

The IXDF602PI meets all mandatory compatibility criteria and provides enhanced electrical performance across multiple parameters while maintaining functional equivalence.

Engineering Selection Recommendations

TSC428EPA (Obsolete): The TSC428EPA is no longer in active production. While 2000 pieces remain available in current inventory, this part number should not be selected for new designs or long-term production commitments due to its obsolete status and limited future availability.

IXDF602PI (Active Substitute): The IXDF602PI is the recommended substitute for the TSC428EPA. This part is currently in active production status with 1112 pieces available in inventory. The IXDF602PI maintains full functional compatibility with the TSC428EPA across all mandatory parameters while providing enhanced electrical performance:

• Extended supply voltage range (4.5V ~ 35V vs. 4.5V ~ 18V)
• Higher peak output current (2A vs. 1.5A)
• Faster switching performance (7.5ns/6.5ns vs. 25ns/25ns)
• Extended operating temperature range (-55°C ~ 150°C vs. -40°C ~ 85°C)
• Additional IGBT gate drive capability

Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL-1 moisture sensitivity classification. The IXDF602PI is suitable for direct substitution in existing TSC428EPA applications without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the IXDF602PI be used as a direct replacement for the TSC428EPA in existing designs?

A: Yes. The IXDF602PI maintains identical package form factor (8-DIP), driven configuration (low-side), channel type (independent dual-channel), and input type (inverting/non-inverting). All electrical parameters of the TSC428EPA fall within the operating range of the IXDF602PI, enabling direct substitution without circuit modification.

Q: What are the key differences between these two parts?

A: The IXDF602PI provides enhanced performance specifications: supply voltage range extends to 35V (vs. 18V), peak output current increases to 2A (vs. 1.5A), switching speed improves to 7.5ns/6.5ns (vs. 25ns), and operating temperature range extends to -55°C ~ 150°C (vs. -40°C ~ 85°C). The IXDF602PI also supports IGBT gate driving in addition to MOSFET operation.

Q: Are there any compatibility concerns with the higher logic voltage threshold (VIH 3V vs. 2.4V) of the IXDF602PI?

A: No. The IXDF602PI's VIH of 3V is higher than the TSC428EPA's 2.4V, but both parts share the same VIL of 0.8V. Logic signals that meet the TSC428EPA's 2.4V threshold will also satisfy the IXDF602PI's 3V threshold. The IXDF602PI is compatible with all logic signal levels that drove the TSC428EPA.

Q: Do both parts have the same regulatory compliance status?

A: Yes. Both the TSC428EPA and IXDF602PI are ROHS3 compliant, REACH unaffected, and classified as MSL-1 (unlimited moisture sensitivity level). Regulatory compliance is maintained across the substitution.

Q: Why is the TSC428EPA listed as obsolete?

A: The TSC428EPA has been discontinued by Analog Devices Inc./Maxim Integrated and is no longer in active production. While inventory remains available, the part is not recommended for new designs due to limited future availability and the availability of superior active alternatives such as the IXDF602PI.

Q: Is the 8-DIP package pinout identical between these parts?

A: Both parts use the 8-DIP (0.300", 7.62mm) package form factor. Pinout compatibility should be verified against the respective device datasheets to ensure correct signal mapping in your specific application, as gate driver IC pinouts can vary between manufacturers even within the same package type.
