The LM5100A/B/C and LM5101A/B/C high-voltage gate drivers are designed to drive both the high-side and the low-side N-Channel MOSFETs in a synchronous buck or a half-bridge configuration. The floating high-side driver is capable of operating with supply voltages up to 100 V. The A versions provide a full 3-A of gate drive, while the B and C versions provide 2 A and 1 A, respectively. The outputs are independently controlled with CMOS input thresholds (LM5100A/B/C) or TTL input thresholds (LM5101A/B/C).

An integrated high-voltage diode is provided to charge the high-side gate drive bootstrap capacitor. A robust level shifter operates at high speed while consuming low power and providing clean level transitions from the control logic to the high-side gate driver. Undervoltage lockout is provided on both the low-side and the high-side power rails. These devices are available in the standard SOIC-8 pin, SO PowerPAD-8 pin, and the WSON-10 pin packages. The LM5100C and LM5101C are also available in MSOP-PowerPAD-8 package. The LM5101A is also available in WSON-8 pin package.

TIDA-01292 — 適用於低頻離線 UPS 和逆變器且不帶散熱器的 650W 功率級參考設計

此參考設計為 650-W 逆變器功率級，專為低頻（基於變壓器）、單相 UPS（由 12-V 電池供電）而設計。此設計利用 SON5x6 封裝且具有極低 RDS (on) 與低閘極電荷 (Qg) 的 TI SMD MOSFET，實現小外型尺寸與高效率實作方案。透過在全橋式功率級的各腳上並聯使用兩個裝置，該功率級消除了散熱器的需求，進而降低整體系統成本。
