TPS92610-Q1: External power dissipation resistors related

Part Number: TPS92610-Q1
Other Parts Discussed in Thread: TIDA-01521

Dear Team,

I have designed Tail Lamp with TPS92610 at LED current of 125mA . I want to perform a test at 85degree C for 24 hrs at 16V input. Referring to TIDA-01521  Table 5 (3rd Column: Tj= 152degC) I fear of IC junction temperature. So, I designed this using figure 25.

But, my issue is as follows:

  • Shall the circuit pass BCI (Bulk Current Injection) test as external resistor is directly connected in between Input supply and LED. My prediction is LED shall glow up in BCI off mode test (as direct path to LED from input side).

Could you correct/suggest me here.

Best Regards,

Sarang
