STM6503REAADG6F

STM6502 has two combined Smart Reset inputs (SR0and SR1) with delayed Smart Reset setup time (t_SRC) programmed by an external capacitor on the SRC pin.STM6503 is similar to STM6502, has two combined delayed Smart Reset inputs (SR0, SR1) and three user-selectable delayed Smart Reset setup time (t_SRC) options of 2 s, 6 s and 10 s through a three-state TSR input pin: when connected to ground, t_SRC= 2 s; when left open, t_SRC= 6 s; when connected to V_CC, t_SRC= 10 s (all the times are minimum).STM6504 has two independent Smart Reset inputs. SR0provides the delayed Smart Reset setup time (t_SRC) function with three user-selectable t_SRCoptions through a three-state TSR input pin: when connected to ground, t_SRC= 2 s; when left open, t_SRC= 6 s; when connected to V_CC, t_SRC= 10 s (all the times are minimum). SRE provides instant reset. SRE is edge-triggered with a special debounce time (t_DEBOUNCE= 240 ms min.) at the falling edge after a valid reset period.STM6505 has two combined delayed Smart Reset inputs (SR0, SR1) and provides an adjustable reset delay setup time via an external capacitor connected to the SRC pin. The RSToutput depends also on the V_CCmonitoring threshold. STM6505 also provides independent low battery detect (BLD) output controlled by the secondary external input voltage V_BAT. V_BATis monitored for low voltage and provides an indication on the battery low detect output pin (BLD). V_BATthreshold is 1.25 V, fixed, and an external resistor divider is to be used to set the actual battery voltage threshold. V_BATthreshold hysteresis is 8 mV typ. (16 mV max.). V_B
