Part Number: DRV8837
hello,i'm new in hardware development and i have some problems with the datasheet, so there we goi'm designing a latching relay driver using DRV8837 and a single coil 3V latching relay, but the logic voltages mentioned in datasheet for IN1 and IN2 confuses me.How can i find the maximum low voltage and the minimum high voltage for IN1 and IN2?thanks for your help
ps. google translate helps me with this question, so ignore the mistakes
Datasheet Page 5 "Absolute Maximum Ratings" and "Recommended Operating Conditions" shows IN1 and IN2 maximum voltage is 7V.
Datasheet Page 6 "CONTROL INPUTS (IN1 or PH, IN2 or EN, nSLEEP)" gives the IN1 and IN2 logic high or low voltage threshold.

In reply to Wang5577:
so, if i have Vcc = 3.3V my minimum high voltage is 3.3 * 0.46 = 1.51V and my maximum low voltage is 3.3 * 0.38 = 1.25V. Thats right?
In reply to Daniel Gasparini:
0.46 or 0.38 are typical number.. Please use minimum voltage for VIL and maximum voltage for VIH
ok, thank you very much!
