  • Product introduction

Der A4910 ist ein dreiphasiger Controller, der mit externen N-Kanal-Leistungs-MOSFETs speziell für Automobilanwendungen verwendet werden kann.

Unique charge pump regulator provides complete (>10 V)Gate driversBatteriespannungen von nur 7 V zu verarbeiten und die Verwendung des A4910 zu ermöglichenGate driversFunktioniert, wenn die Spannung auf 5,5 V abfällt.

The bootstrap capacitor is used to provide the above battery supply voltage required for the N-channel MOSFET. The high-side drive internal charge pump allows DC (100% duty cycle) operation.

Der Baustein bietet die volle Kontrolle über alle sechs Leistungs-MOSFETs in einer dreiphasigen Brücke, so dass der Motor durch blockierende Kommutierung oder sinusförmige Erregung angetrieben werden kann. Die integrierte Frequenzweichensteuerung und die programmierbare induktive Zeit schützen Leistungs-MOSFETs vor Ausfällen.

Der Strom in jeder Halbbrücke kann mit einem integrierten Strommessverstärker gemessen werden. Dabei handelt es sich um drei vom Benutzer konfigurierbare Differenzverstärker mit Masse-Gleichtaktbereich und ausgezeichnetem Einschwingverhalten und Einschwingzeit, sodass sie in Low-Side-Strommessanwendungen eingesetzt werden können.

Integrated diagnostics indicate undervoltage, overtemperature, and power bridging faults, and can be configured to protect the power MOSFETs under most short-circuit conditions. Detailed diagnostics are available in the form of serial data words.

Der A4910 ist in einem kleinen (81 mm2) 48-poligen LQFP-Gehäuse mit freiliegendem Hitzeschild (Suffix JP) erhältlich. Das Gehäuse ist bleifrei (Pb) und verfügt über eine 100% matte Zinn-Leadframe-Beschichtung.
