STM6717/6718/6719/6720
STM6777/6778/6779/6780
Dual/triple ultra-low voltage supervisors
with push-button reset (with delay option)
Features
■ Primary supply (V_CC1) monitor.
Fixed (factory-programmed) reset thresholds:
4.63 V to 1.58 V
■ Secondary supply (V_CC2) monitor
(STM6717/18/19/20/77/78)
■ Fixed (factory-programmed) reset thresholds:
3.08 V to 0.79 V
■ Tertiary supply monitor (using externally
adjustable RSTIN): 0.626 V internal reference
■ RST outputs (push-pull or open drain); state
guaranteed if V_CC1 or V_CC2 ≥ 0.8 V
■ Reset delay time (t_rec) on power-up: 13.2 ms,
210 ms, 900 ms (typ)
■ Manual reset input (MR)
■ Optional delayed manual reset input (MRC)
with external capacitor (STM6777/78/79/80)
■ Low supply current - 11 µA (typ),
V_CC1 = V_CC2 = 3.6 V
■ Operating temperature: –40 °C to 85 °C
(industrial grade)
