Original question:

TPS6594-Q1: TPS659413 and TPS659411 can't output

TPS6594-Q1: TPS659413 EVM

Part Number: TPS6594-Q1
Other Parts Discussed in Thread: DRA829, TDA4VM

Hi Expert,

1. Hardware platform TDA4+ TPS65941213+TPS65941111, Reference schematics: DRA829_TDA4VM_3Ph_Dual_Leo2.0_PDN-0C_v0.17.pdf; FB_B3(Pin 49) connected with VDD_MCUIO_3V3_LS signal;

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1032558/tps6594-q1-tps65941213-can-not-work

1)  VCCA(Pin 4), VIO_IN(Pin 48), PVIN_B1/2/3/4/5(Pin 26/17/45/54/35) , PVIN_LDO/4/3/12(Pin 8/10/12): 3.3V;

2) OVPGDRV(Pin 52): 8.9V;

3) VSYS_SENSE(Pin 51: VCCA_OVP): 3.3V, it is for  overvoltage monitoring.

4) nPWRON/ENABLE(Pin 20): 2V8 (Minimum VIH threshold voltage 1.26V)

5) VOUT_LDOVINT(Pin 2), VOUT_LDOVRTC(Pin 3), OSC32KCAP(Pin 40):  can output 1V8;

6) LEOA_SCLK(Pin 23: GPIO5), LEOA_SDATA(Pin 24: GPIO6): we measured 5MHz waveform, the waveform will disappear after 10s.

7) It is strange that there is 0.15V leakage voltage on VOUT_LDO2(Pin 11: VDD_MCUIO_1V8_REG) of TPS65941213.

we remove R450 resistor, make GPIO4 floating, we abserve things are not changed.

it seems peripheral voltages are ready, but TPS65941213 can not start. 

2. We got TPS659413 EVM, please see following jumper configuration, TPS659413 EVM is same phenomenon with our customized TDA4+TPS65941213+TPS65941111;

After we insert type C USB cable, D3/D4/D5/D6 LED on, fail to install USB driver on windows 7 operation system, success to install Scalable-PMICs-GUI 2.0.0 application software.

we change the other compuster, success to install USB driver on windows 10 operation system, but fail to install Scalable-PMICs-GUI 2.0.0 application software. 

Only VOUT_LDOVINT(Pin 2), VOUT_LDOVRTC(Pin 3), OSC32KCAP(Pin 40):  can output 1V8; the other LDOs and Bucks can not output.

1) We can not download TPS659413 EVM user guide from TI public website, please provide TPS659413 EVM user guide.

2) please provide website link of USB driver and Scalable-PMICs-GUI 2.0.0 application software.

3) TPS659413 I2C device address? is it 0x48 ?

    Hello Jiacai,

    I have assigned this thread to the product expert. Note there can be delays to answer due to US national holiday. 

    Thanks.

    1. Read following register value from 0x48 I2C device address on TPS659413 EVM, how to activate LDOs and Bucks output ? 

    Dev                                   0x01   0x01

    NVM_CODE_1                 0x02   0xF0

    NVM_CODE_1                 0x03   0x07

    INT_TOP                          0x5A   0xAE

    INT_BUCK                       0X5B  0x00

    INT_BUCK1_2                 0x5C  0x00

    INT_BUCK3_4                 0x5D  0x00

    INT_BUCK5                     0x5E  0x00

    INT_LDO_VMON            0x5F  0x10

    INT_LDO1_2                   0x60 0x00

    INT_LDO3_4                   0x61 0x00

    INT_VMON                      0x62 0x01

    INT_GPIO                        0x63 0x08

    INT_GPIO1_8                  0x64 0x08

    INT_STARTUP                0x65 0x02

    INT_MISC                        0x66 0x00

    INT_MODERATE_ERR   0x67 0xA0

    INT_SEVERE_ERR         0x68 0x00

    INT_FSM_ERR                0x69 0x00

    INT_COMM_ERR            0x6A 0x00

    INT_READBACK_ERR   0x6B 0x00

    INT_ESM                         0x6c 0x00

    2. We will further debug TDA4+TPS65941213+TPS65941111 after TPS659413 EVM can output LDOs and Bucks.

    3. So far we can not read registers value from 0x48 I2C device address on our development board(TDA4+TPS65941213+TPS65941111 ) via other I2C probe and read tool.

    1.Ｗe downloaded TPS659413 EVM user guide, TPS659413 EVM can not output LDOs and Bucks because of input overvoltage yesterday, now TPS659413 EVM is OK.

    2. Check registers value of TPS659413 EVM, our development board can work, LDOs and Bucks output correct voltages.
