DRV8832: Peak motor drive output current

Part Number:DRV8832

Hi,

Our customer are evaluating the DRV8832.
Please let me know if there are any problems with the circuit design.

Motor start-up current: 457mA typ
Over load (Lock) current: 1.3A
Rshunt: 0.15 Ω (200mV/0.15 = 1.33A)
VDD: 4.3 V
VSET: 3.12V

According to D/S, "Continuous motor drive output current" is 1A.
Should the current limit be lowered?

On the other hands,I understand that "Peak motor drive output current" is a specification of instantaneous current.
I think this design is not a problem if this specification is considered.

Please give me advice as one of the 20 prototype circuits may have destroyed the IC by EOS.
The cause is unknown.
After power-up, as soon as IN1 or IN2 is set to Hi, Fault is asserted.
The other 19 work fine.

Best regards,
Hiroshi
