The TPS22919 device is a small, single channel load switch with controlled slew rate. The device contains an N-channel MOSFET that can operate over an input voltage range of 1.6 V to 5.5 V and can support a maximum continuous current of 1.5 A.

The switch ON state is controlled by a digital input that is capable of interfacing directly with low-voltage control signals. When power is first applied, a Smart Pull Down is used to keep the ON pin from floating until system sequencing is complete. Once the pin is deliberately driven High (>VIH), the Smart Pull Down will be disconnected to prevent unnecessary power loss.

The TPS22919 load switch is also self-protected, meaning that it will protect itself from short circuit events on the output of the device. It also has thermal shutdown to prevent any damage from overheating.

TPS22919 is available in a standard SC-70 package characterized for operation over a junction temperature range of –40°C to 125°C.

TIDA-01599 — TÜV SÜD 評估工業驅動器的安全扭矩關閉 (STO) 參考設計 (IEC 61800-5-2)

本參考設計概述具有 CMOS 輸入隔離式 IGBT 閘極驅動器的三相逆變器的安全扭矩關閉 (STO) 子系統。STO 子系統採用雙通道架構 (1oo2)，硬體容錯範圍爲 1 (HFT=1)。實作時遵循去能脫扣概念。當雙 STO 輸入 (STO_1 和 STO_2) 變低電位作動時，六個隔離 IGBT 柵極驅動器的一次和二次側對應電源供電將透過負載開關切斷。如此可消除控制馬達並為馬達通電的可能性。STO 參考設計 (1oo2) 已由 TÜV SÜD 進行評估，一般適用於 SIL 3 和 PL e/Cat。3.
