(please go from the outside in t he over current protection.) note 3: when using this product, adjustment is required in accordance with the use environment. when mounting, place as close to the base of this product leads as possible to improve the ripple and noise elimination. note 4: the diag pin is open drain. if not using the diag pin, connect to the gnd. handling precautions (1) please control the input signal in the state to which the v cc voltage is steady. both of the order of the v bb power supply and the v cc power supply are not cared about either. note that if the power supply is switched off as described above, this product 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 rs pin connecting the current detection resistor is connected to a comparator in the ic and also functions as a sensor pin for detecting over current. as a result, over voltage caused by a surge voltage, for example, may destroy the circuit. accordingly, be ca reful of handling the ic or of surge voltage in its application environment.
TPD4144K 2012-02-09 12 description of protection function (1) over-current protection this product incorporates a over-current protection circuit to protec t itself against over-current at startup or when a motor is locked . this protection function detect s voltage generated in the current detection resistor connected to the rs pin. when this voltage exceeds v r ( = 0.5 v typ.), the igbt output, which is on, temporarily s huts down after a delay time , preventing any additional current from flowing to this product. the next a ll ?l? signal releases the shutdown state. (2) under voltage protection this product incorporates under vo ltage protection circuit s to prevent the igbt from operating in unsaturated mode when the v cc voltage or the v bs voltage drops. when the v cc power supply falls to this product internal setting v cc uvd ( = 11 v typ.), all igbt outputs shut down regardless of the input. this protection function has hysteresis. when the v cc power supply reaches 0.5 v higher than the shutdown voltage (v cc uvr ( = 11.5 v typ.)), this product is automatically restored and the igbt is turned on again by the input. diag output is reversed at the time of v cc under-voltage protection. when the v cc power supply is less than 7 v, diag output isn't sometimes reversed. when the v bs supply voltage drops v bs uvd ( = 9 v typ.), the high-side igbt output shuts down. when the v bs supply voltage reaches 0.5 v higher than the shutdown voltage (v bs uvr ( = 9.5 v typ.)), the igbt is turned on again by the input signal. (3) thermal shutdown this product incorporates a thermal shutdown circ uit to protect itself against the abnormal state when its temperature rises excessively. when the temperature of this chip rises to the internal setting tsd du e to external causes or internal heat generation, all igbt outputs shut down regard less of the input. this protection function has hysteresis tsd ( = 50 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 dete ction location, when the ch ip heats up due to the igbt, for example, the differences in distance from the detection locati on in the igbt (the source of the heat) cause differences in the ti me taken for shutdown to occur. therefore, the temperature of the chip may rise higher than the thermal shutdown te mperature when the circuit started to operate. timing chart of under voltage protection note: the above timing chart is considering the delay time safe operating area note 1: the above safe operating areas are tj = 135 c (figure 1). lin ho hin v bs v cc lo diag t on t off t on t off 1.9 peak winding current (a) power supply voltage v bb (v) figure 1 soa at tj = 135 c 0 450 0 400 2
