The capacitor is biased by 6 V (typ.) and must be sufficiently derated for it. Note2: The following formula shows the detection current: IO = VR ÷ RIS (VR = 0.5 V typ.) Do not exceed a detection current of 900 mA when using the IC. Note3: With the combination of Cos and RREF shown in the table, the PWM frequency is around 20 kHz. The IC intrinsic error factor is around 10%. The PWM frequency is broadly expressed by the following formula. (In this case, the stray capacitance of the printed circuit board needs to be considered.) fPWM = 0.65 ÷ (Cos × RREF) [Hz] RREF creates the reference current of the PWM triangular wave charge/discharge circuit. If RREF is set too small it exceeds the current capacity of the IC internal circuits and the triangular wave distorts. Set RREF to at least 9 k Ω. Note4: When using the IC, some adjustment is required in accordance with the use environment. When mounting, place as close to the base of the IC leads as possible to improve the noise elimination. Note5: The FG pin is open drain. When using the FG pin, connect it to, for example, the CPU power supply (5 V) via a pull-up resistor. Note that when the FG pin is connected to a power supply with an voltage equal or higher than the VCC, a protector circuit is triggered so that the current flows continuously. If not using the FG pin, connect to the GND. Note6: If noise is detected on the Hall signal pin, add a CR filter. (recommended 0.1 µF capacitor and 1 kΩ resistor) Handling precautions (1) (2) (3) (4) When switching the power supply to the circuit on/off, ensure that VS < VVSOFF (all IGBT outputs off). At that time, either the VCC or the VBB can be turned on/off first. Note that if the power supply is switched off as described above, the IC may be destroyed if the current regeneration route to the VBB power supply is blocked when the VBB line is disconnected by a relay or similar while the motor is still running. The IS pin connecting the current detection resistor is connected to a comparator in the IC and also functions as a sensor pin for detecting overcurrent. As a result, overvoltage caused by a surge, for example, may destroy the circuit. Accordingly, be careful of handling the IC or of surges in its application environment. The triangular wave oscillator circuit, with externally connected COS and RREF, charges and discharges minute amounts of current. Therefore, subjecting the IC to noise when mounting it on the board may distort the triangular wave or cause malfunction. To avoid this, attach external components to the base of the IC leads or isolate them from any tracks or wiring which carries large current. The PWM of this IC is controlled by the ON/OFF state of the high-side IGBT. 2000-06-12 8/18 TPD4008K Description of Protection Function (1) Overcurrent Overcurrent protection function in this IC detects voltage generated in the current detection resistor connected to the IS pin. When this voltage exceeds VR = 0.5 V (typ.), the high-side IGBT output, which is on, temporarily shuts down after a mask period (approx. 1 µs), preventing any additional current from flowing to the IC. The next PWM ON signal releases the shutdown state. Duty ON PWM reference voltage Duty OFF Triangle wave Mask period + tOFF tOFF tON tON Overcurrent setting Output current Retry Overcurrent shutdown (2) (3) Undervoltage When the VCC power supply falls to the IC internal setting (VCCUVD = 7.5 V typ.), all IGBT outputs shut down regardless of the input. This protection function has hysteresis. When the VCCUVR (= 8.0 V typ.) reaches 0.5 V higher than the shutdown voltage, the IC is automatically restored and the IGBT is turned on again by the input. Overheating When the the temperature of this chip rises due to external causes or internal heat generation and the internal setting TSD reaches 165°C, all IGBT outputs shut down regardless of the input. This protection function has hysteresis (∆TSD = 10°C typ.). When the chip temperature falls to TSD − ∆TSD, the chip is automatically restored and the IGBT is turned on again by the input. Because the chip contains just one temperature detection location, when the chip heats up due to the IGBT, for example, the differences in distance from the detection location in the IGBT (the source of the heat) cause differences in the time taken for shutdown to occur. 0.9 Peak winding current (A) Safe Operating Area 0 0 165 Power supply voltage VBB (V) *: The above safe operating area is Tc = 95°C. If the temperature exceeds this, the safe operation area reduces. *: The above safe operating area includes the overcurrent protection operation area. If the overcurrent protection operation continues, depending on the heat discharge conditions, an overheating protection operation may result. 2000-06-12 9/18 TPD4008K VCEsat – Tj V F – Tj 3.0 IC = 500 mA (V) (V) VCC = 15 V 2.6 FRD forward voltage VF IGBT saturation voltage VCEsat 1.5 2.2 1.8 1.4 1.4 1.3 1.2 1.1 High-side Low-side 1.0 −20 20 60 100 Junction temperature Tj 1.0 −20 140 (°C) 20 60 ICC – VCC 7.0 −20°C 25°C 135°C 25°C Regulator voltage VREG (V) Current dissipation ICC (mA) −20°C 135°C 2.5 2.0 1.5 10 15 6.5 Ireg = 30 mA 6.0 5.5 5.0 5 20 Control power supply voltage VCC (V) 10 tON – Tj 20 (V) tOFF – Tj (µs) 3.0 Output off delay time tOFF (µs) Output on delay tme tON 15 Control power supply voltage VCC 3.0 2.0 1.0 140 (°C) VREG – VCC 3.0 1.0 5 100 Junction temperature Tj VBB = 141 V VCC = 15 V IC = 0.5 A VBB = 141 V VCC = 15 V IC = 0.5 A High-side Low-side 2.0 1.0 High-side Low-side 0 −20 20 60 Junction temperature Tj 100 (°C) 140 0 −20 20 60 100 Junction temperature Tj 140 (°C) 2000-06-12 10/18 TPD4008K V S – Tj Undervoltage protection – Tj 9.0 Undervoltage protection operating voltage VCCUV (V) PWM on-duty set-up voltage VS (V) 6.0 VS 100％ 4.0 VSW 2.0 VS 0% VCC = 15 V 0 −20 20 60 Junction temperature Tj 100 140 (°C) VCCUVD VCCUVR 8.5 8.0 7.5 7.0 6.5 −20 20 60 100 Junction temperature Tj 140 (°C) Current control operating voltage VR (V) V R – Tj 1.0 VCC = 15 V 0.8 0.6 0.4 0.2 0 −20 20 60 Junction temperature Tj 100 140 (°C) 2000-06-12 11/18 0.5 A 23.
