Manufacturer:INTERSIL? Description:applied to the RESET pin while PWM inputs In1,...IN6 are held high (off condition). The FAULT condition can also be set by the controller through an active high signal on the STOP pin. After power-up, the RESET pin must be pulled low before any input signals are activated. The protection circuitry will set a FAULT for short-circuit, earth-fault, over-temperature, or over-voltage conditions as specified. Current signals are sensed through shunts in positive and negative DC bus rails. Earth faults are sensed using the high-side shunt and the signal is fed through an opto-isolator to the protection circuitry. Over-voltage is sensed through a resis- tor divider from the positive DC bus. Over-temperature protection is obtained using a thermistor inside the power mod- ule. A FAULT condition occurs inf the temperature of the power module's IMS substrate exceeds the trip level. The sys- tem is designed for 150% overload for one minute while operating with the specified heat sinks. The controller should shut off the PWM signals if the overload persists for more than one minute. The feedback signals used by the protection circuitry are also available to the controller. The current feedback signal from the low-side shunt is available on the IFB pin at 0.025 V/A. If filter- ing of this signal is required, it should be done by adding a high-impedance buffer stage between signal and filter. The DC bus reference is provided on VFB. This reference has been scaled down by a factor of 100 and should also be protected with a high-impedance buffer stage. The brake function is implemented by connecting a power resistor between the terminals on the Brake terminal block. The value and power of theresistor determines maximum braking ca- pability along with the rating of the brake IGBT. The input signal on IN7 is active low and CMOS or LSTTL compatible. The switching power supply employs an IR2152 self-oscil- lating driver chip in a buck regulator topology to deliver a nominal 15V and 5V DC with respect to the negative bus (N). The power supply feeds the gate drive and protection circuits. The 15V (VCC ) and 5V (VDD) outputs are available on the con- trol interface for powering the user's control logic. |
