(4) Up to 3 mA can flow into VCC when all 3 converters are running in PWM. This resistor causes the UVLO threshold to be shifted accordingly. VINDCDC1 = VINDCDC2 = VINDCDC3 = VCC = VINLDO = 3.6 V, VBACKUP = 3 V, T A = –40°C to 85°C, typical values are at T A = 25°C (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT CONTROL SIGNALS : SCLK, SDAT (input), DCDC1_EN, DCDC2_EN, DCDC3_EN, LDO_EN, DEFLDO1, DEFLDO2 Rpullup at SCLK and SDAT = 4.7 k Ω, VIH High level input voltage 1.3 VCC V pulled to VRTC Rpullup at SCLK and SDAT = 4.7 k Ω, VIL Low level input voltage 0 0.4 V pulled to VRTC IH Input bias current 0.01 0.1 µA CONTROL SIGNALS : HOT_RESET VIH High level input voltage 1.3 VCC V VIL Low level input voltage 0 0.4 V IIB Input bias current 0.01 0.1 µA tglitch Deglitch time at HOT_RESET 25 30 35 ms CONTROL SIGNALS : LOWBAT, PWRFAIL, RESPWRON, INT, SDAT (output) VOH High level output voltage 6 V VOL Low level output voltage IIL = 5 mA 0 0.3 V Duration of low pulse at RESPWRON External capacitor 1 nF 100 ms Resetpwron threshold VRTC falling –3% 2.4 3% V Resetpwron threshold VRTC rising –3% 2.52 3% V 3 Submit Documentation Feedback |
