The ALM2402F-Q1 is a dual-power op amp with features and performance that make this device preferable for resolver-based automotive applications. The high gain bandwidth and slew rate of the device, along with a continuous high-output current-drive capability, make this device an excellent choice to provide a low distortion and differential high amplitude excitation required for modern resolvers. Current limiting and overtemperature detection enhance overall system robustness when driving analog signals over wires that are susceptible to faults.

The ALM2402F-Q1 rail-to-rail output, enabled by the low Rds(on) PMOS and NMOS transistors, keeps the power dissipation low. The small HTSSOP package with thermal pad and low RθJA allows users to deliver high currents to loads while minimizing board space. This minimized board space is one of the key advantages offered by the ALM2402F-Q1 when used in modern hybrid and electric vehicles.

The ALM2402F-Q1 maximum output voltage is determined using the Maximum Output Voltage vs Frequency plot at the bottom of this page.

TIDM-02009 — 經 ASIL D 安全概念評估的高速牽引、雙向 DC/DC 轉換參考設計

此參考設計展現如何以單一 TMS320F28388D 即時 C2000 MCU 控制 HEV 或 EV 牽引逆變器和雙向 DC-DC 轉換器。牽引控制運用軟體式解析器轉數位轉換器 (RDC) 將馬達驅動至高達 20,000 RPM 的高速。DC-DC 轉換器則採用尖峰電流模式控制 (PCMC) 技術,以及全橋相移式轉換器 (PSFB) 拓撲與同步整流 (SR) 機制。牽引變流器級使用由 UCC5870-Q1 智慧閘極驅動器驅動的碳化矽 (SiC) 功率級。PCMC 波形是使用最先進的 PWM 模組和比較器子系統 (CMPSS)中的內建傾斜補償產生。ASIL 分解系統功能安全概念已通過 TÜV (...)
