DRV8838: drv8838

Part Number: DRV8838

Tool/software:

Hi Technical Support,

For part DRV8838 ( H Bridge Motor Driver) when in sleep mode as shown in datasheet snippet:

IVMQ VM sleep mode supply current VM = 5 V; VCC = 3 V; nSLEEP = 0 30 95 nA

VCC sleep mode supply current VM = 5 V; VCC = 3 V; nSLEEP = 0 5 25 nA

Is this the total current the ENTIRE chip will consume( all pins taken into account ?)

or is there other leakage current that should be considered  when the IC is in "sleep Mode"  Pin(nSleep) = Logic zero 

for absolute total current consumed ?

Thank you

    Hi John,

    During sleep mode, IVMQ and IVCCQ will be what the device consumes during sleep mode from the power supplies. IVMQ is the quiescent current draw during sleep mode for the H-bridges and VCCQ supplies the digital logic during sleep mode. The device should not consume any more power than then the sum of the two maximum values. There could also be additional leakage current on the output pins. IOFF specs the output leakage current ranges from -200 to 200nA when VOUT = 0V. 

    Is there a specific system requirement of current draw you're trying to stay under during sleep mode?

    Best,

    David
