28 / 101 page  DA9062 PMIC for Applications Requiring up to 8.5 A Datasheet Revision 3.8 15-Feb-2022 CFR0011-120-00 28 of 99 © 2022 Renesas Electronics 5.8 Internal Oscillator Unless otherwise noted, the following is valid for TJ = -40 °C to +125 ºC, VSYS = 2.8 V to 5.5 V. Table 19: Internal Oscillator Electrical Characteristics Parameter Symbol Test Conditions Min Typ Max Unit Oscillator frequency fOSC OSC_FRQ = 0000 5.7 6 6.3 MHz Note 1 Oscillator frequency can be further adjusted by about ±10 %, see Section 8.14. 5.9 System Supply Voltage Supervision Unless otherwise noted, the following is valid for TJ = -40 °C to +125 ºC, VSYS = 2.8 V to 5.5 V. Table 20: System Supply Voltage Supervision Electrical Characteristics Parameter Symbol Test Conditions Min Typ Max Unit Under-voltage lockout lower threshold VPOR_LOWER 2.0 V Under-voltage lockout upper threshold VPOR_UPPER 2.3 V VSYS under-voltage lower threshold VDD_FAULT_LOWER Note 1 2.5 2.8 3.25 V VSYS under-voltage lower threshold accuracy VSYS_LOWER -2% +2% VSYS hysteresis VDD_FAULT_HYS Note 2 100 200 450 mV VSYS upper threshold VDD_FAULT_UPPER -2% VDD_FAULT_LOWER + VDD_FAULT_HYS +2% Reference voltage VREF -1.25% 1.2 +1% V VREF decoupling capacitor CVREF 2.2 µF Reference current resistor RIREF -1% 200 +1% k Note 1 Can be set in 50 mV steps via register VDD_FAULT_ADJ in register CONFIG_B, setting VDD_FAULT_LOWER ≥ 2.65 V avoids LDOCORE dropout, see Section 5.4.3. Note 2 Can be set in 50 mV steps via register VDD_HYST_ADJ in register CONFIG_B. |
