Orderable Information

10.1 Device Nomenclature

Table 10-1 shows how to decode the function of the device based on the device ordering code, while
Table 10-2 shows the sequence configuration based on the device ordering code. See Figure 5-1 for more information regarding how to decode the device part number.

Table 10-1 Device Comparison Table
ORDERING CODE FUNCTIONS EN PINS DEFAULT ALT FUNC. PINS TIME SLOT (μsec) I2C ADDR. RESET DELAY (msec) WATCHDOG PEC(1) I2C PULL-UP VOLTAGE (V)
TPS38700C04NRGER Sequencer, NEM_PD Push-Pull Low Open-Drain 625 3C 16 Disabled Enabled 3.3
(1) For parts with PEC enabled:
  1. PEC calculation is based on initializing to 0xFF.
  2. In case of a PEC violation there needs to be a subsequent I2C transaction before NIRQ is asserted.
  3. If incorrect PEC is given it will assert NIRQ.
  4. If there is an extra byte after successfully writing the correct PEC byte, NIRQ will be asserted and the write will fail.
