The ISO5852S device is a 5.7-kV RMS, reinforced isolated gate driver for IGBTs and MOSFETs with split outputs, OUTH and OUTL, providing 2.5-A source and 5-A sink current. The input side operates from a single 2.25-V to 5.5-V supply. The output side allows for a supply range from minimum 15 V to maximum 30 V. Two complementary CMOS inputs control the output state of the gate driver. The short propagation time of 76 ns provides accurate control of the output stage.

An internal desaturation (DESAT) fault detection recognizes when the IGBT is in an overcurrent condition. Upon a DESAT detect, a mute logic immediately blocks the output of the isolator and initiates a soft-turnoff procedure which disables the OUTH pin and pulls the OUTL pin to low over a time span of 2 µs. When the OUTL pin reaches 2 V with respect to the most-negative supply potential, V EE2, the gate-driver output is pulled hard to the V EE2 potential, turning the IGBT immediately off.

When desaturation is active, a fault signal is sent across the isolation barrier, pulling the FLT output at the input side low and blocking the isolator input. Mute logic is activated through the soft-turnoff period. The FLT output condition is latched and can be reset only after the RDY pin goes high, through a low-active pulse at the RST input.

When the IGBT is turned off during normal operation with a bipolar output supply, the output is hard clamp to V EE2. If the output supply is unipolar, an active Miller clamp can be used, allowing Miller current to sink across a low-impedance path which prevents the IGBT from dynamic turnon during high-voltage transient conditions.

The readiness for the gate driver to be operated is under the control of two undervoltage-lockout circuits monitoring the input-side and output-side supplies. If either side has insufficient supply, the RDY output goes low, otherwise this output is high.

The ISO5852S device is available in a 16-pin SOIC package. Device operation is specified over a temperature range from –40°C to +125°C ambient.

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.

TIDA-00917 — 適用於具有短路保護功能和電流緩衝器的並聯 IGBT 的閘極驅動器參考設計

輸出功率額定值較高的電源轉換設備需要並聯絕緣柵雙極電晶體 (IGBT)，因為單一 IGBT 無法提供所需的負載電流。此參考設計實作強化隔離式 IGBT 閘極控制模組，以半橋配置驅動並聯 IGBT。並聯 IGBT 會在閘極驅動器（驅動強度不足）和系統層級帶來挑戰，需在兩個 IGBT 維持相等的電流分配，同時確保快速導通和關閉。此參考設計使用強化隔離式 IGBT 閘極驅動器，並具備去飽和偵測與軟關閉等整合式功能，以在發生故障時保護 IGBT。透過外部 BJT 電流升壓級獲得更高的閘極驅動電流 (15A)，無需犧牲軟關閉功能。此外，此設計展示了在並聯操作 IGBT 時避免閘極電流迴路的機制。
