ZHCSJ10B September 2006 – November 2018 TPS2376-H
PRODUCTION DATA.
The 25 kΩ PD signature is measured by applying two voltages between 2.7 V to 10.1 V, that are at least 1 V apart, to the PD's PI and measuring the current. The resistance is calculated as a ΔV/ΔI, with an acceptable range of 23.75 kΩ to 26.25 kΩ.
The TPS2376-H is in detection mode whenever the supply voltage is below the lower classification threshold. The TPS2376-H draws a minimum of bias power in this condition, while PG and RTN are high impedance and the circuits associated with ILIM and CLASS are disabled. The DET pin is pulled to VSS during detection. Current flowing through R(DET) to VSS shown in Figure 13 produces the detection signature.
