개요

Description

IR21271 typically denotes an Introduction to International Relations course. It usually covers:
- Goals and scope of IR; core concepts
- Theoretical frameworks: realism, liberalism, constructivism
- Key actors: states, IGOs, NGOs, MNCs
- Core topics: war/peace, diplomacy, international law, trade/economics, human rights, globalization, environment
- International organizations and regimes; diplomacy and negotiation
- Research methods: basic IR methods, case studies
- Assessments: exams, essays, presentations, group work
Prerequisites vary; often no strict prerequisites or at most an introductory social sciences background. If IR21271 refers to a different program or institution, please share the context for a precise syllabus.

Equivalent

IR21271 is a bootstrapped high‑side/low‑side gate driver. There isn’t an exact one‑to‑one cross‑reference. Functionally similar parts from other vendors include TI’s UCC27201/UCC27517 and ON Semiconductor’s NCP81239 (two‑channel high/low‑side drivers), with ROHM/ST equivalents as well. For a precise cross, provide the datasheet details (V_B range, UVLO, drive current, package).

Features

IR21271 is a high‑voltage, high‑speed gate driver for MOSFET half‑bridges with a floating high‑side. Key features:
- Two independent outputs: HO (high‑side) and LO (low‑side)
- Floating high‑side drive via bootstrap supply (VB–VS)
- TTL/CMOS‑friendly inputs; logic supply from Vcc
- Undervoltage lockout (UVLO) on both channels with hysteresis
- Shoot‑through protection and programmable deadtime
- Fast gate drive with high peak source/sink current
- Fault/diagnostic reporting and protection features
- External bootstrap capacitor required for VB–VS
- Available in common packages (e.g., SOIC/DIP)
Note: exact voltage ratings and current specs depend on the specific variant; consult the datasheet for your part number for precise limits.

Pinout

- Pin count: 16 pins (DIP16/SO-16).
- Function: High-voltage, high-speed dual gate driver for a half-bridge (drives N-channel MOSFETs/IGBTs). Provides independent high-side (HO) and low-side (LO) outputs, uses a bootstrap VB–VS supply for the high-side, inputs HIN/LIN, and includes UVLO/SD protection.

Manufacturer

- Manufacturer: International Rectifier (IR), now part of Infineon Technologies.
- What kind of company: A semiconductor company specializing in power management and power electronics, producing devices such as MOSFETs, IGBTs, and gate-driver ICs.

Application

IR21271 is a high-voltage, high-speed, dual-channel gate driver for N‑channel MOSFETs in half-bridge/topology (bootstrap type). It provides UVLO, dead-time, shoot-through protection, and fast turn-off.
Typical application areas:
- Gate drive for two-MOSFET bridges in SMPS (DC-DC, AC-DC, isolated)
- Motor drives (BLDC/PMSM, stepper) and inverters
- Solar inverters, UPS, and other industrial/power electronics
- Automotive power electronics

Package

IR21271 is a high-side/low-side gate driver supplied in an 8-pin package, commonly DIP-8 or SO-8 (D-8). Exact option depends on the supplier—check the datasheet for the exact package.
