9 / 44 page ![]() www.ams.com/AS5030 Revision 2.4 9 - 44 AS5030 Datasheet - Electrical Character i s t ics 6.8 8-bit PWM Output 6.9 Serial 8-bit Output 3-wire Interface. 2-wire Interface. Symbol Parameter Conditions Min Typ Max Units NPWM PWM resolution 8bit 2 µs/step PWMIN PWM pulse width Angle = 0° (00H) 1.66 2.26 2.85 µs PWMAX PWM pulse width Angle = 358.6° (FFH) 427 578 731 µs PWP PWM period Over full temperature range 1 1. The tolerance of the absolute PWM pulse width and frequency can be eliminated by using the duty cycle tON/(tON+tOFF) for angle measurement(see 1-Wire PWM Connection on page 16). 428 581 734 µs fPWM PWM frequency 1 / PWM period 1.72 kHz Hyst Digital hysteresis 2 2. Hysteresis may be temporarily disabled by software(see 16-bit Write Command on page 24). At change of rotation direction 1 bit Symbol Parameter Conditions Min Typ Max Units fCLK Clock frequency Normal operation 6MHz tCLK 166.6 ns fclk,P Clock frequency During OTP programming 250 500 kHz Symbol Parameter Conditions Min Typ Max Units fCLK Clock frequency Normal operation 0.1 6 MHz tCLK 166.6 10,000 ns fclk,P Clock frequency During OTP programming 250 500 kHz tTO Synchronization timeout Rising edge of CLK to internally generated chip select on pin DX 16.6 27 34.3 ms Hyst Digital hysteresis 1 1. Hysteresis may be temporarily disabled by software. At change of rotation direction 1 bit |
