41、D. 2 VOUT Output Supply Voltage. When VCC is greater than VBATT and above the reset threshold, VOUT connects to VCC. When VCCfalls below VBATT and is below the reset threshold, VOUT connects to VBATT. Connect a 0.1Fcapacitor from VOUT to GND. Connect VOUT to VCCif no backup battery is used. 3 VCC In
42、put Supply Voltage, 5V Input. 4 GND Ground. 0V reference for all signals. 5 BATT ON Battery-On Output. When VOUT switches to VBATT, BATT ON goes high. When VOUT switches to VCC, BATT ON goes low. Connect the base of a PNP through a current-limiting resistor to BATT ON for VOUT current requirements g
43、reater than 250mA. 6 LOWLINE LOWLINE output goes low when VCC falls below the reset threshold. It returns high as soon as VCC rises above the reset threshold. 7 OSC IN External Oscillator Input. When OSC SEL is unconnected or driven high, a 10A pull-up connects from VOUT to OSC IN, the internal osci
44、llator sets the reset and watchdog timeout periods, and OSC IN selects between fast and slow watchdog timeout periods. When OSC SEL is driven low, the reset and watchdog timeout periods may be set either by a capacitor from OSC IN to ground or by an external clock at OSC IN. 8 OSC SEL Oscillator Sel
45、ect. When OSC SEL is unconnected or driven high, the internal oscillator sets the reset delay and watchdog timeout period. When OSC SEL is low, the external oscillator input (OSC IN) is enabled. OSC SEL has a 10A internal pull-up. 9 PFI Power-Fail Input. This is the noninverting input to the power-f
46、ail comparator. When PFI is less than 1.25V, PFO goes low. When PFI is not used, connect PFI to GND or VOUT. 10 PFO Power-Fail Output. This is the output of the power-fail comparator. PFO goes low when PFI is less than 1.25V. This is an uncommitted comparator, and has no effect on any other internal
47、 circuitry. 11 WDI Watchdog Input. WDI is a three-level input. If WDI remains either high or low for longer than the watchdog timeout period. WDO goes low and reset is asserted for the reset timeout period. WDO remains low until the next transition at WDI. Leaving WDI unconnected disables the watchd
48、og function. WDI connects to an internal voltage divider between VOUT and GND, which sets it to mid-supply when left unconnected. 12 CE OUT Chip-Enable Output. CE OUT goes low only when CE IN is low and VCC is above the reset threshold. If CE IN is low when reset is asserted, CE OUT will stay low for 15 s or until CE IN goes high, whichever occurs first. 13 CE
