Part Number: DRV8432
hi Team,
we are using your DRV8432 for our design, it's for TEC drive, disign is below, now we found the TEC output was lower than PVDD, for example,
PVDD=15V,but the output is 13.2V, 88% efficiency, as mentioned in datasheet, it's 97%, what cause this, can we improve it?
The DRV841x2 are high-performance, integrated dual
full-bridge motor driver with an advanced protection
system.
Because of the low RDS(on) of the H-Bridge MOSFETs
and intelligent gate drive design, the efficiency of
these motor drivers can be up to 97%. This high
efficiency enables the use of smaller power supplies
and heatsinks, and the devices are good candidates
for energy-efficient applications.
