TPD4008K 2000-06-12 8/18 external parts standard external parts are shown in the following table. part recommended value purpose other c 1 , c 2 , c 3 2.2 f bootstrap capacitor (note1) r 1 0.62 ? 1% (1 w) current detection (note2) c 4 1000 pf 5% pwm frequency setup (note3) r 2 27 k ? 5% pwm frequency setup (note3) c 5 10 f control power supply stability (note4) c 6 0.1 f v reg power supply stability (note4) r 3 5.1 k ? fg pin pull-up resistor (note5) note1: although the required bootstrap capacitance value with the motor drive conditions, care must be taken to keep the capacitor voltage above 5 v at startup and during drive. the capacitor is biased by 6 v (typ.) and must be sufficiently derated for it. note2: the following formula shows the detection current: i o = v r ris (v r = 0.5 v typ.) do not exceed a detection current of 900 ma when using the ic. note3: with the combination of cos and r ref 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.) f pwm = 0.65 (cos r ref ) [hz] r ref creates the reference current of the pwm triangular wave charge/discharge circuit. if r ref is set too small it exceeds the current capacity of the ic internal circuits and the triangular wave distorts. set r ref to at least 9 k ? . 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 v cc , 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 f capacitor and 1 k ? resistor) handling precautions (1) when switching the power supply to the circuit on/off, ensure that v s < vv s off (all igbt outputs off). at that time, either the v cc or the v bb 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 v bb power supply is blocked when the v bb line is disconnected by a relay or similar while the motor is still running. (2) 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. (3) the triangular wave oscillator circuit, with externally connected c os and r ref , 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. (4) the pwm of this ic is controlled by the on/off state of the high-side igbt.
TPD4008K 2000-06-12 9/18 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 v r = 0.5 v (typ.), the high-side igbt output, which is on, temporarily shuts down after a mask period (approx. 1 s), preventing any additional current from flowing to the ic. the next pwm on signal releases the shutdown state. (2) undervoltage when the v cc power supply falls to the ic internal setting (v cc uvd = 7.5 v typ.), all igbt outputs shut down regardless of the input. this protection function has hysteresis. when the v cc uvr ( = 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. (3) 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. safe operating area * : 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. duty on overcurrent setting pwm reference voltage duty off t off t on t on mask period + t off overcurrent shutdown retry triangle wave output current 0.9 0 165 peak winding current (a) power supply voltage v bb (v) 0
