  • [FAQ] AM64x/243x: How to Use Keyring for Authentication of Application Images in MCU+ SDK

    Part Number: AM2434 On HSSE devices, the SYSFW supports the Keyring feature which extends the Root of Trust ( RoT ) to auxiliary keys. This enables the authentication of the application images using these auxiliary keys apart from the programmed SMPKH…

  • [FAQ] REF80/81: TI precision voltage reference devices

    TI precision voltage references.

  • [FAQ] BQ25173: Why does the BQ25173 charge a supercapacitor slowly or at reduced current, and how can the maximum charge current be achieved? BQ25173 BQ25173-Q1

    Part Number: BQ25173 Slow charging or reduced current from the BQ25173 is almost always caused by thermal regulation (TREG) . When the supercapacitor starts from 0 V and the input voltage is, say, 5 V, the full input-to-output voltage drop appears across…

  • [FAQ] BQ25173: Can two BQ25173 devices be operated in parallel for higher charge current, and what is the recommended method? BQ25173 BQ25173-Q1

    Part Number: BQ25173 Yes, two BQ25173 devices can be paralleled to increase total output current (up to 1.6 A combined). The recommended method uses a slight offset in the output voltage setpoints between the two devices: one unit is set slightly higher…

  • [FAQ] BQ25173: How should multiple supercapacitors be balanced when charged in series with the BQ25173? BQ25173 BQ25173-Q1

    Part Number: BQ25173 The BQ25173 does not have built-in cell balancing . For series-connected supercapacitors, external balancing resistors placed in parallel across each capacitor are the standard recommended approach. A single-cell supercap (rated…

  • [FAQ] BQ2517x: How should the TS pin be configured if no NTC thermistor is used, and can the TS pin be used as a charge enable/disable? BQ25171-Q1, BQ25173-Q1, BQ25170, BQ25172, BQ25173, BQ25176J, BQ25176K, BQ25176M, BQ25175

    Part Number: BQ25172 If no NTC temperature monitoring is needed, connect a 10 kOhm resistor from TS to GND . This biases the TS pin within the normal operating range (~350–380 mV with the internal 38 µA current source), preventing any false hot/cold…
