Alpha & Omega Semiconductor Inc. AIP3P15A060Q4N

Overview

AIP3P15A060Q4N from Alpha & Omega Semiconductor is a 600V, 15A dual-in-line intelligent power module (IPM) integrating three-phase inverter IGBTs with built-in bootstrap diodes, short-circuit protection, controllable over-temperature monitoring (VOT), and fault output (VCF). It features 2000V_rms/min isolation, UL 1775 recognition, and an integrated PFC diode (cathode P2/anode P3) for single-stage AC–DC conversion. Used in air-conditioner compressors and washing machine motor drives.

For engineers reviewing the AIP3P15A060Q4N datasheet, pinout, applications, or equivalent options, key selection considerations include its 600V/15A inverter rating, PFC diode integration, VOT temperature sensing output, UVLO/OT/CSC protection architecture, and IPM-3C normal-terminal package with 26-pin layout.

Technical Context

This IPM integrates six trench-shielded planar-gate IGBTs (three high-side, three low-side) with ultra-fast recovery freewheeling diodes per phase. Its control logic includes Schmitt-trigger inputs (3V/5V compatible), independent high-side bias supplies (VB(U/V/W)), and a shared VDD supply with under-voltage lockout (UVLO) thresholds of 11.4V trip / 11.9V reset.

Protection functions are hardware-based and fully integrated: short-circuit detection via CSC pin with 0.48V reference, controllable over-temperature trip (adjustable 100–140°C via OT pin pull-down), and open-drain fault output (VCF) that signals SC, UV, or OT events with configurable pulse width (20µs fixed or RC-timed up to ~1ms).

FAQ

What is the maximum DC-link voltage supported by the AIP3P15A060Q4N?

The AIP3P15A060Q4N supports a maximum DC-link supply voltage of 450V (VPN) under continuous operation and 500V for non-repetitive surge conditions. Its inverter IGBTs are rated for 600V V_CES, enabling reliable operation up to 400V DC-link in recommended conditions per the datasheet's Recommended Operation Conditions table. Exceeding 400V risks triggering self-protection limits.

How does the VOT pin on the AIP3P15A060Q4N provide temperature monitoring?

The VOT pin delivers an analog voltage proportional to the internal LVIC die temperature: 1.05V at 25°C and 2.77V at 90°C, with ±3.5°C accuracy. This linear output allows direct ADC sampling by a 3.3V or 5V MCU. For low-voltage MCUs, a clamp diode is recommended to prevent overvoltage, and a 2kΩ/10nF RC filter is advised to suppress noise before the ADC input.

Can the AIP3P15A060Q4N be used without connecting the PFC diode pins P2 and P3?

Yes-the AIP3P15A060Q4N functions as a standard three-phase inverter IPM even when P2 and P3 are left unconnected. These pins are dedicated to the integrated 650V/30A PFC diode; omitting their connection disables the PFC function but does not affect inverter operation. The device remains fully functional for motor drive-only applications without boost-stage rectification.

What protection features are implemented in hardware within the AIP3P15A060Q4N?

The AIP3P15A060Q4N implements five hardware-based protections: (1) short-circuit detection via CSC pin with 0.48V reference, (2) control-supply UVLO (11.4V trip), (3) high-side bias UVLO (9.5V trip), (4) controllable over-temperature shutdown (100–140°C via OT pin), and (5) fault signaling through open-drain VCF. All operate independently of firmware and respond within microseconds.

What is the purpose of the NC pin (Pin 1) on the AIP3P15A060Q4N?

Pin 1 on the AIP3P15A060Q4N is designated NC (No Connection) and must remain unconnected in all designs. It serves no electrical function and is reserved for mechanical or future revision purposes. Connecting this pin may cause undefined behavior or damage; the datasheet explicitly states it is not bonded internally and should be left floating.
