IOUT_LEAK – -40.0 – – +5.0 +5.0 µA Switch Turn-on threshold for Supply over-voltage (VPWR -GND) VD_GND(CLAMP) 58 – 66 V Switch turn-on threshold for Drain-Source over-voltage (measured at IOUT = 500 mA VDS(CLAMP) 58 – 66 V Switch turn-on threshold for Drain-Source over-voltage difference from one channel to the other in parallel mode (@ IHS = 500 mA) ΔV DS(CLAMP) -2.0 – +2.0 V Current Sensing Ratio(13) CSNS_ratio bit = 0 (high current mode) CSNS_ratio bit = 1 (low current mode) CSR0 CSR1 – – 1/1500 1/500 – – – Minimum measurable load current with compensated error(14) I_LOAD_MIN – – 50 mA CSNS leakage current in OFF state (CSNSx_en = 0, CSNS_ratio bit_x = 0) ICSR_LEAK -4.0 – +4.0 µA Systematic offset error (see Current Sense Errors) I_LOAD_ERR_SYS – 5.5 – mA Random offset error I_LOAD_ERR_RAND -125 – 125 mA Notes: 13. Current Sense Ratio CSRx = ICSNS / (IHS[x] +I_LOAD_ERR_SYS) 14. See note (15), but with ICSNS_MEAS obtained after compensation of I_LOAD_ERR_RAND (see Activation and Use of Offset Compensation). Further accuracy improvements can be obtained by performing a 1- or 2 point calibration (see Application Note) 15. ESRx_ERR=(ICSNS_MEAS / ICSNS_MODEL) -1, with ICSNS_MODEL = (I(HS[x])+ I_LOAD_ERR_SYS) * CSRx , (I_LOAD_ERR_SYS defined above, see section Current Sense Error Model). With this model, load current becomes: I(HS[x]) = ICSNS / CSRx - I_LOAD_ERR_SYS Table 3. Static Electrical Characteristics (continued) Unless specified otherwise: 8.0 V ≤ V PWR ≤ 36 V, 3.0 V ≤ VDD ≤ 5.5 V, - 40 °C ≤ TA ≤ 125 °C, GND = 0 V. Typical values are average values evaluated under nominal conditions TA = 25 °C, VPWR = 28 V & VDD = 5.0 V, unless specified otherwise. Parameter Symbol Min Typ Max Unit |
