Undervoltage Lockout Protection This family provides undervoltage lockout protection both (logic low-side circuitry) power supply (high-side circuitry) power supply. Figure used illustrate this concept; VBS) plotted over time waveform crosses UVLO threshold (VCCUV+/- VBSUV+/-) undervoltage protection enabled disabled. Upon power-up, should voltage fail reach VCCUV+ threshold, will turn-on. Additionally, voltage decreases below VCCUV- threshold during operation, undervoltage lockout circuitry will recognize fault condition shutdown high- low-side gate drive outputs, FAULT will transition state inform controller fault condition. Upon power-up, should voltage fail reach VBSUV threshold, will turn-on. Additionally, voltage decreases below VBSUV threshold during operation, undervoltage lockout circuitry will recognize fault condition, shutdown high-side gate drive outputs UVLO protection ensures that drives external power devices only when gate supply voltage sufficient fully enhance power devices. Without this feature, gates external power switch could driven with voltage, resulting power switch conducting current while channel impedance high; this could result very high conduction losses within power device could lead power device failure.

IRS2607D recommended trapezoidal motor control, even external bootstrap network employed parallel. summary bootstrap state follows: Bootstrap turns-off (immediately) stays when least following conditions met: goes/is high goes/is high 1.1*VCC) Bootstrap turns-on when: high (low side ~1.1(VCC)) after transition from output tri-state) goes (<1.1*VCC) before fixed time 20us. after transition from output tri-state) goes (<1.1(VCC)) before retriggerable time 20us. this case time counter kept reset state until goes high (>1.1VCC).

However, real inverter circuit, voltage swing does stop level negative bus, rather swings below level negative bus. This undershoot voltage called "negative transient". circuit shown Figure depicts three phase inverter; Figures show simplified illustration commutation current between parasitic inductances power circuit from bonding tracks lumped together each IGBT. When high-side switch below voltage voltage drops associated with power switch parasitic elements circuit.

Figure Negative transient IRS2607D VBS=15V Even though IRS2607D been shown able handle these large negative transient conditions, highly recommended that circuit designer always limit negative transients much possible careful layout component use. Layout Tips Distance between high voltage components: It's strongly recommended place components tied floating voltage pins near respective high voltage portions device. Please Case Outline information this datasheet details.
Ground Plane: order minimize noise coupling, ground plane should placed under near high voltage floating side.
Gate Drive Loops: Current loops behave like antennas able receive transmit noise (see Figure 24). order reduce coupling improve power switch turn on/off performance, gate drive loops must reduced much possible. Moreover, current injected inside gate drive loop IGBT collector-to-gate parasitic capacitance. parasitic auto-inductance gate loop contributes developing voltage across gate-emitter, thus increasing possibility self turn-on effect.

This component should placed close possible pins order reduce parasitic elements. Routing Placement: Power stage parasitic elements contribute large negative voltage transients switch node; recommended limit phase voltage negative transients. order avoid such conditions, recommended minimize high-side emitter low-side collector distance, minimize low-side emitter negative rail stray inductance. However, where negative spikes remain excessive, further steps taken reduce spike.
