DRV10987: is warming up

Part Number:DRV10987

hi, i drive our motor with drv10987

my motor parameters

rph=1.552

kt=13

3 phase bldc motor with 10 poles.

the motor work in 24v.

the drv is getting 24v.

this is my configuration:

unsigned char buf_conf5[] = {DRV10987Q_CONFIG1_Reg , 0x04 , 0x4A}; 

unsigned char buf_conf10[] = {DRV10987Q_CONFIG2_Reg , 0x0F , 0x3B};

unsigned char buf_conf11[] = {DRV10987Q_CONFIG3_Reg , 0xCB , 0x86};

unsigned char buf_conf12[] = {DRV10987Q_CONFIG4_Reg , 0x23 , 0x67};

unsigned char buf_conf13[] = {DRV10987Q_CONFIG5_Reg , 0x3B , 0x0D};

unsigned char buf_conf14[] = {DRV10987Q_CONFIG6_Reg , 0x79 , 0x63};

unsigned char buf_conf15[] = {DRV10987Q_CONFIG7_Reg , 0x27 , 0x67};

the motor is running. but, the drv is warming up a lot and when i start the motor sometimes it takes couple of tries before the motor start working.

can you see something wrong in my configuration?

thank you,

liraz
