IR2152 Half-Bridge Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2152 is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in power management applications. The device features RC input circuitry, dual synchronous channels, and a 600V maximum bootstrap voltage rating. The IR2152 is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. Substitute parts must maintain functional compatibility across driven configuration, channel type, gate type support, and electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2152 is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Must be Half-Bridge
• Channel Type: Must be Synchronous
• Number of Drivers: Must be 2
• Gate Type: Must support IGBT and N-Channel MOSFET
• Input Type: Must be RC Input Circuit
• High Side Voltage - Max (Bootstrap): Must be 600V or greater
• Package / Case: Must be 8-DIP (0.300", 7.62mm) for through-hole mounting compatibility
• Operating Temperature Range: Must encompass -40°C ~ 150°C (TJ)

The L6571B from STMicroelectronics meets all substitution criteria. While supply voltage range and peak output current specifications differ, these variations remain within acceptable operational bounds for half-bridge gate driver applications and do not preclude functional substitution.

Engineering Selection Recommendations

The L6571B is the qualified substitute for the IR2152. Selection rationale is based on the following factors:

Product Status: The IR2152 is obsolete, whereas the L6571B maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance: The L6571B is ROHS3 compliant, meeting current regulatory requirements for electronic components in regulated markets. The IR2152 is RoHS non-compliant, which may present procurement restrictions in certain jurisdictions.

Functional Equivalence: Both devices maintain identical driven configuration, channel type, gate type support, input circuitry, bootstrap voltage rating, operating temperature range, and physical package dimensions. These parameters ensure direct functional substitution in half-bridge gate driver applications.

Performance Characteristics: The L6571B provides equal or superior peak output current capability (170mA source, 270mA sink versus 125mA source, 250mA sink), supporting equivalent or enhanced gate drive performance. The supply voltage range of the L6571B (10V ~ 16.6V) is a subset of the IR2152 range (10V ~ 20V); applications operating above 16.6V supply voltage require design review.

Frequently Asked Questions (FAQ)

Q: Can the L6571B directly replace the IR2152 in existing PCB designs?

A: Yes, the L6571B is a direct pin-compatible replacement. Both devices use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pinout for half-bridge gate driver applications. No PCB layout modifications are required.

Q: What is the impact of the L6571B's lower maximum supply voltage (16.6V vs. 20V)?

A: Applications operating within the L6571B supply voltage range of 10V ~ 16.6V experience no functional impact. Designs requiring supply voltages between 16.6V and 20V must be evaluated for alternative solutions or design modification.

Q: Does the L6571B's higher peak output current affect circuit design?

A: The L6571B provides higher peak output current (170mA source, 270mA sink) compared to the IR2152 (125mA source, 250mA sink). This enhancement improves gate drive capability and reduces switching transition times, benefiting overall system performance without requiring design changes.

Q: Are there compliance differences between the IR2152 and L6571B?

A: Yes. The L6571B is ROHS3 compliant, meeting current environmental and regulatory standards. The IR2152 is RoHS non-compliant. For applications subject to RoHS regulations, the L6571B is the required choice.

Q: What is the REACH status of both devices?

A: Both the IR2152 and L6571B are REACH Unaffected, indicating no restrictions under REACH regulations.
