Description

The PT7M62xx serials of ultra-low-power voltage detectors monitor battery, power-supply and system voltages. Each circuit includes a precision bandgap reference, a comparator, internally trimmed resistor networks that set specified trip thresholds, and an internal 5% threshold hysteresis circuit. Output is asserted when VCC rises above VTH+ (VTH+ = VTH-×1.05) and remains asserted until VCC falls below the internal VTH-. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from +1.8V to +5V in 100mV increments. The series are voltage detectors with a propagation delay of 20μs(VCC rise).
The family is available with three output stage options:

  • Push-pull with active-low output, push-pull with active-
  • High output, and open drain with active-low output.

Features

  •  Highly precision: -0.7%~+0.5% (25°C); ±1%(-10°C to 60°C, for PT7M62xxxx); ±1.5%(-10°C to 60°C, for PT7M62xxxxB)
  • Low power consumption: 0.9uA @ 3V Vcc
  • Detect voltage range: 1.8 to 5V in 100mV increments
  • Operating voltage range: 1.2V ~ 5.5V
  • Output configuration: N-channel open drain or CMOS
  • Special threshold voltage product according to customer need
