21 / 71 page ![]() Data Sheet 21 Rev 1.0, 2015-03-27 - TLE82452-3SA Power Supply Attention: Voltage Ratings for Charge Pump caps: CPC1/CPC2: Vmin=VBATmax + 10V, CCPOUT: Vmin=16V Power-on wake-up time T WU –– T WU =65536/ ( F SYS/kHz) + 0.1 ms 1)Timer starts after writing to the CLK-DIV register, (CSN goes high) all supplies are above the UV thresholds and RESN pin is high. Output stages are functional after T WU 2) P_6.12.14 Charge Pump Charge pump voltage V CP_OUT V BAT+8 – V BAT +13 3) V P_6.12.15 Charge pump clock frequency F CP –65 – KHz F SYS = 6 MHz 4) P_6.12.16 Charge pump warning threshold voltage V CPOUT_W V BAT+7 – V BAT+ 8.5 V P_6.12.17 Charge pump undervoltage threshold voltage V CPOUT_UV V BAT +4.5 – V BAT +5.5 V P_6.12.18 Charge pump overvoltage clamp V CPOUT_OV – 48.5 – V P_6.12.19 1) Not subject to production test, specified by design. 2) To guarantee a proper Autozero result there must not be any I LOAD during power-on wake-up (Chapter 8.7). 3) Will not exceed V CPOUT_OV. 4) Parameter not subject to production test, specified by design. Table 5 Electrical Characteristics: Power Supply (cont’d) V BAT = 8 V to 17 V, VDDx = 4.75 V to 5.25 V, Tj = -40 °C to +150 °C, CPC1 and CPC2 = 27nF CPCOUT = 220nF, all voltages with respect to ground (GNDD), positive current flowing into pin (unless otherwise specified) Parameter Symbol Values Unit Note / Test Condition Number Min.
