Concerns of escalating system complexity and reliability are being addressed by pursuing a strategy of high-level integration and component count reduction. The IRS26302DJ high-voltage IC (HVIC) offering from International Rectifier is well suited to today’s needs as it integrates all system gate drive requirements in a single package, while boosting system safety through a host of protection features and system intelligence through enhanced communication with the microcontroller. Simplified Solution The IRS26302DJ is a high-voltage, high speed power MOSFET and IGBT gate driver with three independent high- and low-side referenced output channels for threephase applications and an additional low-side channel that can be employed for either PFC or brake IGBT driving operation. Reduction in system component count and complexity as a result of the additional low-side gate driver and integrated bootstrap functionality translates into improved reliability, reduced returns from the field and ultimately lower overall system cost for the appliance manufacturer. • Micro/mini inverter drives • General purpose inverters • Motor control For more information, call +(33) 1 64 86 49 53 or +49 6102 884 311 or visit us at www.irf.com 10206FS For more information, call +(33) 1 64 86 49 53 or +49 6102 884 311 or visit us at www.irf.com 10206FS IRS26302DJPbF – Fully Protected Three Phase Gate Drive IC Featuring Extra Channel Typical Connection Diagram Comprehensive over-current protection offered through three different current monitors in the IRS26302D DC+ shunt current monitor DC+ BUS VCC VDC VCC VDC HIN 1,2,3 LIN 1,2,3 PFCIN/BRIN FLT / EN RCIN GF VSDC PFCOUT/BROUT PFCTRIP/BRTRIP RCIN VS1 VS(x3) VS2 VS3 To Load ITRIP COM 3rd shunt current monitor DC- BUS DC- shunt current monitor With the IRS26302DJ, International Rectifier has set a new benchmark in system over-current protection standards by way of three independent current monitors that detect excess current in three shunt resistors – one each on DC+ bus, DC- bus and either PFC or brake circuitry to provide a comprehensive current protection scheme for appliance inverter applications. Advanced input filters on all current monitors effectively prevent nuisance trips due to noise in the system’s environment. DC+ current Monitor Circuitry • Unique DC+ current monitor offers the only means to detect phase-earth shorts inside the motor (insulation break-down etc) • DC+ current monitor circuit is completely self-biasing, requiring no external supply An enable function is available to terminate all outputs simultaneously and is provided through a bidirectional pin combined with an open-drain FAULT pin. Fault signal is provided to indicate that an over-current or VCC UVLO under-voltage Enhanced System Intelligence Enhanced communication with the microcontroller after occurrence of a fault condition is realized by a fault diagnostic reporting protocol in the IRS26302DJ. After each fault event, a diagnostic feature, when enabled, can communicate to the controller which fault happened in the system (UVcc, ITRIP, Symbol Definition Max Test Conditions MDT DT matching 50ns VIN = 0V and 5V without external deadtime MT Delay matching time (tON, tOFF) 60ns VIN = 0V and 5V with external deadtime larger than DT PM Pulse width distortion 75ns PW input - 10µs Outstanding deadtime and delay matching in IRS233(0,2)(D) along with low pulse width distortion ITRIP Fault Set LIN2 = L, LIN1,3 = H; HINx = H Wait tDIAGIN LO 1,2,3 FLT / EN = 0 COM ITRIP YES PFCTRIP Fault NO Set LIN3 = L, LIN1,2 = H; HINx = H Wait tDIAGIN ITRIP Shunt DC- YES NO VS1,2,3 FLT / EN = 0 GF, PCFtrip). If diagnostic is enabled by forcing all HIN = High and LIN = High, the HVIC enters into a handshake mode during which all outputs remain off, the automatic fault clear function is disabled and FLT/EN is in HZ (refer to Figure). The HVIC fault register is now ready for queries from the microcontroller for true fault reporting. This feature offers superior intelligence to the system that is especially useful for safety considerations during re-start. shutdown has occurred. Over-current fault conditions are cleared automatically after an externally programmed delay via an RC network connected to the RCIN input. The IRS26302DJ also features enhanced input filters that avoid small pulse commands which can potentially reach the gates of the switches in the inverter. This is one of the sources of problems in the field and usually it is difficult to find. The typical effect is that sometimes inverters return from the field damaged with one destroyed leg without an apparent root cause. In addition to improved filtering techniques, the IRS26302DJ also guarantees outstanding matching in propagation time on all channels as well as dead-time automatically inserted when external deadtime is lower than a minimum safe limit.
