Hi Robert,
Sorry for the delay.
I'm not sure what you mean by starting / restarting USB charging. For example, are you writing EN_CHARGER bit = 1 and then EN_CHARGER bit = 0 to disable and then writing to 1 again to re-enable? I tried on my EVM and…
Part Number: TPS659037 Other Parts Discussed in Thread: TWL6032EVM Hi, Is there any example on how to measure a temperature with a NTC connected to GPAD_IN1 and a resistor to GPADC_VREF? A schematic is displayed on page 77 of the TPS659037 datasheet (slis165e…
Hi Logan, I think your understanding is correct. TWL6032 only supports 1 5V input by default, a second 5V VAC requires external chip. See Figure 4-23 in the datasheet. Alternatively, the second 5V can be bucked down and treated as VBAT, like they do…
Hi Kevin H,
I think that workaround may not work as expected if charger is enabled when battery is removed. In that case, the charger will be supplying pack+ and so the NMOS gate will stay high even though nothing is connected. You may want to experiment…
Hi Charlie,
Toggling CHRG_DET_N has no effect after the first rising edge (For A2B4 OTP). Rising edge sets a latch to use CIN_LIMIT instead of E_CIN_LIMIT that can only be reset by removing charger.
VIH for most of the digital signals appears to be expected…
