Part Number: TX7316


Hello,

My customer has a question about TX7316.

[Q]

Please tell me how to configure (H/W and S/W) the 4.8A mode in 5-level mode.

(refer to D/S P.1 1 Features)

Best Regards,

Hiroshi Katsunaga

    here are the description : 

    8.4.1 4A Mode
    The pulser of the device can be configured to give out 4A current when device is used in 5-level mode. To get
    the 4A output keep the voltage level of AVDDP/M_HV_A and AVDDP/M_HV_B supplies same. Set the register
    bits 4A_CNTRL_1 and 4A_CNTRL_2 to '1'. Writing these registers configures the device in 3-level mode even
    though pin LVL_3Z_5 is connected to logic level ‘1’. So configure the rest of the setting of device assuming it is
    in 3-level mode. So group A and group B pulser will get enabled together and gives out a maximum drive
    strength of 4.8 A at 100-V supply.

    Thanks!

    Hi Xiaochen-san,

    Thank you for your fast response.
    I almost understood, but I have one question.
    I confirmed the D/S (SLOS950), but I can not found the registers 4A_CNTRL_1 and 4A_CNTRL_2.
    Please tell me the register address and the bit field.

    Best Regards,

    Thank you for your confirmation.

    OK, I wait for the D/S to be updated.

    Thank you for your cooperation.
