STM6717/6718/6719/6720
STM6777/6778/6779/6780
Dual/triple ultra-low voltage supervisors
with push-button reset (with delay option)
Features
â Primary supply (VCC1) monitor.
Fixed (factory-programmed) reset thresholds:
4.63 V to 1.58 V
â Secondary supply (VCC2) monitor
(STM6717/18/19/20/77/78)
â Fixed (factory-programmed) reset thresholds:
3.08 V to 0.79 V
â Tertiary supply monitor (using externally
adjustable RSTIN): 0.626 V internal reference
â RST outputs (push-pull or open drain); state
guaranteed if VCC1 or VCC2 ⥠0.8 V
â Reset delay time (trec) on power-up: 13.2 ms,
210 ms, 900 ms (typ)
â Manual reset input (MR)
â Optional delayed manual reset input (MRC)
with external capacitor (STM6777/78/79/80)
â Low supply current - 11 µA (typ),
VCC1 = VCC2 = 3.6 V
â Operating temperature: â40 °C to 85 °C
(industrial grade)
SOT23-5 (WY)
SOT23-6 (WB)
