1. General Device Information

️· Device: VN920SP-E
️· The document details the electrical characteristics of this device, with a heavy focus on current sensing features.

2. Current Sense Parameters (Table – “I_OUT /I_SENSE versus I_OUT”)

This is the core of the document. The table details how the output current (I_OUT) relates to the current sensed (I_SENSE) under different conditions. Key parameters:

️· K1: I_OUT / I_SENSE ratio @ I_OUT = 1A. Values range from 3300 to 6000 (typical value 4400). Drift (dK1/K1) is +/- 10%.
️· K2: I_OUT / I_SENSE ratio @ I_OUT = 10A. Values range from 4200 to 6000 (typical value 4900). Drift (dK2/K2) is +/- 8%.
️· K3: I_OUT / I_SENSE ratio @ I_OUT = 30A. Values range from 4200 to 5500 (typical value 4900). Drift (dK3/K3) is +/- 6%.
️· ISENSEO: Analog sense leakage current. Max 10 µA.
️· VSENSE: Max analog sense output voltage. 2V @ VCC=5.5V, 4V @ VCC>8V
️· VSENSEH: Sense voltage in overtemperature conditions. 5.5V
️· RVSENSEH: Analog sense output impedance in overtemperature condition. 400 Ohms.
️· tDSENSE: Current sense delay response to 90% ISENSE. Max 500 µs.

3. Key Electrical Characteristics (Outside the Main Table)

️· Figures: Figures 5 and 6 visually represent Iout/Isense characteristics and switching performance, respectively.

4. Temperature Dependency

️· The current sense ratios (K1, K2, K3) have drift specifications given as a percentage (dK1/K1, dK2/K2, dK3/K3) over a temperature range (-40°C to +150°C). The specified values are provided for different temperature ranges.
