Product Summary
The TPS3828-50DBVR family of supervisors provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power-on, RESET is asserted when supply voltage VDD becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active as long as VDD remains below the threshold voltage VIT-.
Parametrics
Absolute maximum ratings: (1)Supply voltage, VDD: 6 V; (2)RESET, RESET, MR, WDI: –0.3 V to (VDD + 0.3 V); (3)Maximum low output current, IOL: 5 mA; (4)Maximum high output current, IOH: –5 mA; (5)Input clamp current range, IIK (VI < 0 or VI > VDD): ±10 mA; (6)Output clamp current range, IOK (VO < 0 or VO > VDD): ±10 mA; (7)Operating free-air temperature range, TA: –40℃ to 85℃; (8)Storage temperature range, Tstg: –65℃ to 150℃; (9)Soldering temperature: 260℃.
Features
Features: (1)Power-On Reset Generator With Fixed Delay Time of 200 ms (TPS3823/4/5/8) or 25 ms (TPS3820); (2)Manual Reset Input (TPS3820/3/5/8); (3)Reset Output Available in Active-Low (TPS3820/3/4/5), Active-High (TPS3824) and Open-Drain (TPS3828); (4)Supply Voltage Supervision Range 2.5 V, 3 V, 3.3 V, 5 V; (5)Watchdog Timer (TPS3820/3/4/8); (6)Supply Current of 15 μA (Typ); (7)SOT23-5 Package; (8)Temperature Range: –40℃ to 85℃.
