Touchstone Semiconductor Introduces Its First Proprietary, Low-Power Comparators for Ultra-Low Power Applications

Share Article

Touchstone’s first single-supply, low power, low-voltage analog comparators are designed for power-sensitive applications, such as telemetry, battery monitoring, mobile and other handheld devices.

Both products are Touchstone Semiconductor’s first comparators in its NanoWatt Analog™ high-performance analog integrated circuits portfolio.

Touchstone Semiconductor, a developer of high-performance analog integrated circuit solutions, today announced the TS9001-1 and the TS9001-2, single-supply, low power analog comparators plus voltage reference integrated circuits. Both products are Touchstone Semiconductor’s first analog comparator products in its “NanoWatt Analog™” high-performance analog integrated circuits portfolio.

Both the TS9001-1 and the TS9001-2 are electrical specification improvements over the MAX9117 and the MAX9118, respectively. Both TS9001s incorporate a +1.252V reference with a 1% initial accuracy, a 33% initial accuracy improvement over the MAX9117 or the MAX9118. The TS9001-1 offers a robust push-pull output stage with increased output current drive while the TS9001-2 offers an open-drain output stage that can be used in mixed-voltage systems design. Both TS9001s are fully specified to operate from +1.6V to 5.5V supplies while consuming less than 0.65µA supply current.

The TS9001s are optimally designed for low-voltage, power-sensitive applications. These applications include: telemetry and remote systems, medical instrumentation, battery monitoring/management, as well as mobile and other hand-held communication devices.

Key specifications:

  •     Improved electrical performance over MAX9117-MAX9118
  •     Guaranteed to operate down to +1.6V
  •     Ultra-low supply current: 0.6µA
  •     Internal +1.252V ±1% reference
  •     Input voltage range extends 200mV outside-the-rails
  •     No phase reversal for overdriven inputs
  •     Output stage: push-pull (TS9001-1), open-drain (TS9001-2)
  •     Crowbar-current-free switching
  •     Internal hysteresis for clean switching

The TS9001-1 and the TS9001-2 are fully specified over the -40°C to +85°C industrial temperature range and are both offered in a space-saving 5-pin SC70 packages. TS9001 prices start at $0.95 each in 1000-piece quantities.
