D.2 Pin # Name Description 21 SD (3) It is an active low, dual function input/output pin. It is internally pulled high to +5V by 2.74K Ω. As a low input it shuts down all MOSFETs regardless of the Hin and Lin signals. SD is internally activated by the over-temperature shutdown, overcurrent limit, and desaturation protection Desaturation shutdown is a latching feature. Over-temperature shutdown, and over-current limit are not latching features. SD can be used to shutdown all MOSFETs by an external command. An open collector switch shall be used to pull down SD externally. SD can be used as a fault condition output. Low output at SD indicates a latching fault situation. 22 Flt (3) It is a dual function input/output pin. It is an active low input, internally pulled high to +5V by 2.74K Ω. If pulled down, it will freeze the status of all the six MOSFETs regardless of the Hin and Lin signals. As an output, Pin 13, reports desaturation protection activation. When desaturation protection is activated a low output for about 9 μsec is reported. If any other protection feature is activated, it will not be reported by Pin 22. 23 Flt-Clr (3) is a fault clear input. It can be used to reset a latching fault condition, due to desaturation protection. Pin 23 an active high input. It is internally pulled down by 2.0KΩ. A latching fault due to desaturation can be cleared by pulling this input high to +5V by 200-500Ω, or to +15V by 3-5KΩ, as shown in Fig. 6. It is recommended to activate fault clear input for about 300 μsec at startup. © 2004 Sensitron Semiconductor • 221 West Industry Court • Deer Park, NY 11729 • (631) 586 7600 FAX (631) 242 9798 • www.sensitron.com • [email protected] • Page 8 SENSITRON SEMICONDUCTOR SPM6M080-010D TECHNICAL DATA Datasheet 4118, Rev.

D.2 c- System Start Up Sequence: Activate fault clear input for about 300 μsec at startup. The micro-controller enable output is inverted and fed to the second DS34C87 control input. When the controller is in disable mode, the Flt-clr is enabled and Phase C low-side MOSFET is turned on. This allows for the bootstrap circuit of the high-side MOSFET of Phase C to be charged. At the same time, the high-side bootstrap circuits of Phases A and B will charge through the motor winding. Once the controller is enabled, PWM signals of all channels should start. Fig. 6 shows a recommended startup circuit.

D.2 e- Active Bias For Desaturation Detection Circuit: The desaturation detection is done by diode D2 for the high side MOSFET Q1H, and by diode D3 for the low side MOSFET Q1L. The internal detection circuit, input DSH for the high-side and input DSL for the low-side, is biased by the local supply voltage VCC for the low side and VBS for the high side. When the MOSFET is on the corresponding detection diode is on. The current flowing through the diode is determined by the internal pull resistor, R1 for the high side and R2 for the low side. To minimize the current drain from VCC and VBS, R1 and R2 are set to be 100KΩ. Lower value of R1 will overload the bootstrap circuit and reduce the bootstrap capacitor holding time. To increase the circuit noise immunity, an active bias circuit is used to lower R1 and R2 when the corresponding MOSFET is off by monitoring the input voltage at both DSH, DSL inputs. If the inputs at DSH drops below 7V the active bias is disabled. The active bias circuits result in reducing R1 or R2 to about 110 Ω when the corresponding input is above 8V, as shown in Fig. 8. This active circuit results in higher noise immunity.

D.2 f- Limitation With Trapezoidal Motor Drive In trapezoidal motor drives, two phases are conducting while the third phase is off at any time. In Fig. 9 shows the voltage waveform across one phase, during intervals t1 and t2, the MOSFET is off while the active bias circuit is above 8V, and below 15V. This results in activating the active pull up circuit and reducing the corresponding R1 or R2 down to about 110 Ω. A high current will flow from VCC or VBS through R2 or R1 and the motor winding during intervals t1, and t2. This results in draining the bootstrap capacitor voltage quickly. Contact the factory for adjustments to satisfy trapezoidal motor drive applications using this module. The adjustment will disable the internal pull up circuit.

D.2 g Increasing Current Limit Window: The adjustable over-current shutdown reference at Pin25 is internally set to 1.64V corresponding to 34A. A voltage divider reference is used as shown in Fig.16. Internal pull-up to +5V is 31.6KΩ, pull down to ground is 10KΩ, and hysteresis resistance to SD is 49.9KΩ. The re-start delay time, off time, is about 70 usec. In order to increase the over-current shutdown reference to 2.8V, corresponding to 57A peak current, an external pull-up resistance R is needed. It is recommended to add R=9 KΩ between Pins 21 and 25. The corresponding off time will be about 170usec. The additional R=9 KΩ will reduce the high level of SD to 4.4V.
