PT7M6218-6250 CL/CH/NL
Voltage Detector
Features
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.
Highly precision: ±1.5% (25°C); ±2.5%(-40°C
to +85°C);
Low power consumption: 1.0μA @ 3.6V 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
Operating temperature range: -40°C to + 85°C
Detect voltage temperature characteristics: 2.5%
