Alpha & Omega Semiconductor Inc. AIP3N15A060Q4

Overview

AIP3N15A060Q4 from Alpha & Omega Semiconductor is a 600V/15A three-phase inverter Intelligent Power Module (IPM) with integrated trench-shielded planar gate IGBTs, built-in bootstrap diodes with 100Ω current-limiting resistors, and comprehensive protection including controllable over-temperature (OT), short-circuit (CSC), and under-voltage lockout (UVLO) functions. It delivers 38 × 24 × 3.6 mm DIP package isolation of 2000 Vrms/min and supports AC 100–240 Vrms motor drives for air-conditioners and washing machines.

For engineers reviewing the AIP3N15A060Q4 datasheet, pinout, applications, or equivalent options, key selection considerations include its dual-function VCF pin (fault output + enable input), NTC-based temperature monitoring, 125°C case operating temperature, and low-side-only short-circuit protection requiring external shunt resistor and RC filtering.

Technical Context

The AIP3N15A060Q4 integrates six IGBTs and six freewheeling diodes in a 3-phase bridge configuration, with independent high-side (UH/VH/WH) and low-side (UL/VL/WL) PWM inputs using Schmitt-trigger receivers compatible with 3V/5V logic. Its protection architecture features separate UVLO thresholds for control supply (VDD: 11.4 V trip) and high-side bias (VDB: 9.5 V trip), plus OT trip level configurable via OT pin connection (120°C default).

Short-circuit detection operates exclusively on low-side IGBTs using CSC pin sensing with 0.48 V reference voltage and 5 µs withstand time at 400 V supply; fault signaling is delivered through open-drain VCF with fixed (≥20 µs) or RC-controlled pulse width. Thermal management relies on an embedded NTC thermistor (R25 = 84.83 kΩ, B = 4092 K) connected to pin 17.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous output current rating of the AIP3N15A060Q4 at 80°C case temperature?

The AIP3N15A060Q4 supports 10 A continuous output phase current at T_C = 80°C, as specified in its Absolute Maximum Ratings table. This derating from 15 A at 25°C reflects thermal limitations of the internal IGBTs and must be accounted for in heatsink design. The AIP3N15A060Q4 datasheet confirms this value applies under TJ < 150°C conditions with proper thermal management.

How does the VCF pin function as both a fault output and enable input in the AIP3N15A060Q4?

The VCF pin on the AIP3N15A060Q4 is an open-drain output that pulls low during SC, UV, or OT faults. When held low externally (e.g., by MCU GPIO), it disables all low-side IGBTs while leaving high-side drivers operational - enabling controlled shutdown sequences. This dual behavior is documented in Figure 5 and page 6 of the AIP3N15A060Q4 datasheet, with timing details for pulse width control via RC network.

Can the AIP3N15A060Q4 provide short-circuit protection for high-side IGBTs?

No, the AIP3N15A060Q4 implements short-circuit protection exclusively for low-side IGBTs via the CSC pin and external shunt resistor. High-side IGBTs rely on system-level current sensing or software-based monitoring. This limitation is explicitly stated in Figure 6 and page 8 of the AIP3N15A060Q4 datasheet, which specifies "Low-side Operation Only" for SC protection.

What NTC thermistor parameters are provided for temperature monitoring in the AIP3N15A060Q4?

The AIP3N15A060Q4 embeds an NTC thermistor with R₂₅ = 84.83 kΩ and B-value of 4092 K (B_25/100), as listed in the Electrical Characteristics table on page 6. These values enable accurate temperature calculation across –40°C to 150°C using standard Steinhart-Hart equations, and are validated in Figure 4's resistance-vs-temperature curve for the AIP3N15A060Q4.

What is the recommended mounting torque for the AIP3N15A060Q4's M3 screws?

The AIP3N15A060Q4 requires M3 mounting screws tightened to 0.69 N·m (typical), with allowable range of 0.59–0.78 N·m per the Mechanical Characteristics table on page 7. This specification ensures optimal thermal contact between the IPM baseplate and heatsink without damaging the ceramic substrate - critical for maintaining the 125°C case temperature limit in the AIP3N15A060Q4.
