Alpha & Omega Semiconductor Inc. AIP3N15A060Q4N

Overview

AIP3N15A060Q4N from Alpha & Omega Semiconductor is a 600V/15A three-phase intelligent power module (IPM) integrating trench-shielded planar gate IGBTs, built-in bootstrap diodes with 100Ω current-limiting resistors, UVLO, controllable over-temperature protection, NTC-based temperature monitoring, and short-circuit protection with CSC input. It delivers motor drive functionality for AC 100–240Vrms low-power inverter systems.

For engineers reviewing the AIP3N15A060Q4N datasheet, pinout, applications, or equivalent options, key selection considerations include its IPM-3A package, 2000V_rms/min isolation rating, 125°C case temperature limit, dual-function VCF pin (fault output + enable), and low-side-only short-circuit protection architecture.

Technical Context

The AIP3N15A060Q4N integrates six IGBTs and six freewheeling diodes in a 3-phase bridge topology, with independent high-side and low-side gate drivers. Its control logic includes Schmitt-trigger inputs compatible with 3V/5V logic, under-voltage lockout on both VDD (11.4V trip) and VDB (9.5V trip), and OT protection triggered at 120°C when OT pin is tied to VDD.

Short-circuit detection uses an external shunt resistor and RC-filtered CSC input with 0.48V reference threshold; fault response is implemented via open-drain VCF output with configurable pulse width (20µs fixed or RC-controlled up to ~1ms). Thermal monitoring relies on an integrated NTC thermistor (R₂₅ = 84.83kΩ, B = 4092K).

FAQ

What is the maximum continuous output current rating of the AIP3N15A060Q4N?

The AIP3N15A060Q4N is rated for 15A continuous output current at case temperature T_C = 25°C. This rating decreases to 10A at T_C = 80°C due to thermal derating. The device supports 30A peak current for pulses under 1ms. These values are specified in the Absolute Maximum Ratings table on page 3 of the AIP3N15A060Q4N datasheet and reflect actual inverter leg performance under defined thermal conditions.

How does the VCF pin function in the AIP3N15A060Q4N?

The VCF pin in the AIP3N15A060Q4N serves two distinct roles: it outputs an open-drain fault signal (for short-circuit, under-voltage, or over-temperature events) and acts as an enable input. When pulled low, it shuts down all low-side IGBTs immediately. Fault pulse width can be fixed at ≥20µs or extended using an RC network (e.g., 2.2MΩ + 1nF yields ~1.07ms). This dual functionality is detailed in Figures 4–5 and page 6 of the AIP3N15A060Q4N datasheet.

Does the AIP3N15A060Q4N provide short-circuit protection for both high-side and low-side IGBTs?

No-the AIP3N15A060Q4N implements short-circuit protection exclusively for the low-side IGBTs. Detection occurs via the CSC pin using an external shunt resistor and RC filter, triggering shutdown within 5µs. High-side IGBTs lack dedicated SC sensing; their protection relies on system-level timing controls and the low-side shutdown action. This architecture is explicitly stated on page 1 and confirmed in Figure 6 of the AIP3N15A060Q4N datasheet.

What is the purpose of the OT pin on the AIP3N15A060Q4N?

The OT pin on the AIP3N15A060Q4N configures the over-temperature protection trip point. Connecting OT to VDD sets the trip temperature to 120°C; leaving it open or pulling it down with resistors adjusts the threshold to 100°C, 110°C, or 130°C. This allows designers to tailor thermal shutdown behavior to specific heatsink and ambient conditions without modifying firmware. Details are provided in Note 4 (page 5) and Figure 9 of the AIP3N15A060Q4N datasheet.

Can the AIP3N15A060Q4N operate with 3.3V logic inputs?

Yes-the AIP3N15A060Q4N features Schmitt-trigger input receivers compatible with both 3V and 5V logic levels. Its input threshold is 2.6V typical (ON) and 1.2V typical (OFF), with 1.1V hysteresis, ensuring noise immunity and reliable switching across standard microcontroller I/O voltages. This is verified in the Electrical Characteristics table on page 5 of the AIP3N15A060Q4N datasheet.
