TPS22996H-Q1: Power management forum

Part Number: TPS22996H-Q1

Tool/software:

What is the least amount of delay between VINx and VOUTx for the TPS22996H-Q1 dual channel load switch? And what will be the corresponding I(on) and R(t) value?

The datasheet mentions a delay of 320 us at RL = 10Ω, CL = 0.1uF, I(on) = 100 uA for VBIAS=VON=VIN=5 V, is there any possibility to achieve a lesser delay and turn-on time (as less as possible)? We are using VBIAS=VON=VIN=3.3 V.

  • Hello Bharath,

    Find the Tdelay dependency  wrt ION.

    tD Delay Time RL = 10Ω, CL = 0.1uF, ION = 100 uA   384   µs
    tD Delay Time RL = 10Ω, CL = 0.1uF, ION = 100 uA, -55°C ≤ Tj  ≤ 125°C   320   µs
    tD Delay Time RL = 10Ω, CL = 0.1uF, ION = 20 uA, -55°C ≤ Tj  ≤ 125°C   1080   µs
    tD Delay Time RL = 10Ω, CL = 0.1uF, ION = 250 uA, -55°C ≤ Tj  ≤ 125°C   164   µs

    Thanks
