Intelligent power switches from STMicroelectronics are compact, efficient, and robust

意法半導(dǎo)體的智能功率開(kāi)關(guān)具有緊湊、高效、穩(wěn)健的優(yōu)勢(shì)

STMicroelectronics’IPS4140HQand IPS4140HQ-1are richly featured four-channel intelligent power switches, combining a compact 8 mm x 6 mm footprint, 80m? RDS(on) (max.) per channel, and 10.5V-36V operating range with extensive diagnostic and protection features.

意法半導(dǎo)體的IPS4140HQ和IPS4140HQ-1是功能豐富的四通道智能功率開(kāi)關(guān)，采用緊湊型8 mm x 6 mm封裝，每通道80m? RDS(on) (最大值)，同時(shí)具有10.5V-36V工作電壓范圍，以及廣泛的診斷和保護(hù)功能。

Suited to driving any kind of resistive, capacitive, or inductive load with one side connected to the ground, the switches are used in programmable logic controllers, peripheral input/output ports of industrial PCs, and numerical control machines.

此類(lèi)開(kāi)關(guān)適用于驅(qū)動(dòng)容性、阻性和感性負(fù)載，該負(fù)載一端接本功率開(kāi)關(guān)，另一端接地?？蛇m用于可編程邏輯控制器、工業(yè)PC的外設(shè)輸入/輸出端口和數(shù)控機(jī)床。

With a preset current limit of 0.7A in the IPS4140HQ and 1.0A in the IPS4140HQ-1, the switches also tolerate 41 V maximum applied voltage to enhance system safety and reliability.

IPS4140HQ和IPS4140HQ-1的預(yù)設(shè)電流限制分別為0.7A和1.0A，開(kāi)關(guān)還可以承受41 V的最大施加電壓，以提高系統(tǒng)的安全性和可靠性。

Per-channel protection and diagnostics include short-circuit protection, as well as temperature monitoring that can turn off and restart overloaded channels independently to maximize system-level fault tolerance and simplify automated recovery. In addition, case-overtemperature monitoring that shuts down the entire device restarts channels sequentially to avoid excessive peak-current demand on the power supply. A dedicated open-drain output pin for each channel provides an external indication of overtemperature status.

每通道具有獨(dú)立保護(hù)，包括短路保護(hù)，以及每通道溫度監(jiān)測(cè)，可獨(dú)立關(guān)閉/重啟過(guò)載通道，以顯著提高系統(tǒng)級(jí)容錯(cuò)能力并簡(jiǎn)化自動(dòng)恢復(fù)。此外，殼溫監(jiān)測(cè)會(huì)關(guān)斷整個(gè)器件，并按順序重啟通道，以避免電源上的峰值電流需求過(guò)大。芯片具有每通道診斷功能，各通道的專用開(kāi)漏輸出引腳可提供過(guò)溫狀態(tài)的故障指示。

Further protection and diagnostic features include short-circuit protection, output-current limiting, undervoltage lockout (UVLO), ground-disconnection protection, and input-overvoltage protection. In addition, an output voltage clamp provides fast demagnetization for inductive loads.

高級(jí)保護(hù)和診斷功能包括短路保護(hù)、輸出電流限制、欠壓鎖定 (UVLO)、接地?cái)嚅_(kāi)保護(hù)和輸入過(guò)壓保護(hù)。此外，輸出電壓鉗為電感負(fù)載提供了快速退磁功能。

Made using ST’s VIPower technology, these intelligent power switches can withstand single-pulse avalanche energy (EAS) up to 2.5 J single channel and I/O pins and are compatible with 5 V and 3.3 V logic. Transient robustness meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (burst), and IEC 61000-4-5 (Surge) IEC 61000-4, and electromagnetic compatibility is compliant with IEC 61131-2 for industrial equipment.

智能功率開(kāi)關(guān)采用意法半導(dǎo)體的VIPower技術(shù)制造，可承受高達(dá)2.5 J的每通道單脈沖雪崩能量 (EAS)，I/O引腳的兼容5 V和3.3 V邏輯。瞬態(tài)穩(wěn)健性符合IEC 61000-4-2(ESD)、IEC 61000—4-4（快速脈沖）和IEC 61000——4-5（浪涌）IEC 61000-4標(biāo)準(zhǔn)，而電磁兼容性則符合工業(yè)設(shè)備的IEC 61131-2標(biāo)準(zhǔn)。

The IPS4140HQ and IPS4140HQ-1 are available now in the 8 mm x 6 mm QFN48 package, priced from $ 2.59 for orders of 1000 pieces.
