Product Description

The PT7M7433/34/35 are single-level battery monitors with internal hysteresis. These devices are offered with single low-battery output indicators which can be used to indicate three battery conditions: good (operate system in normal mode), weak (operate system in lowpower mode), or empty (disable the system). The PT7M7433/34/35 are user-adjustable threshold voltages permitting the user to select the hysteresis range and consequently the sensitivity of the system to noise. A wide hysteresis range also prevents chattering that can result due to battery recovery after load removal.

Features

  • User-Adjustable Low/High Thresholds with 615mV Internal Reference
  • Low Current (1.5μA typ)  Single Low-Battery Outputs
  • Push-Pull LBO, Open-Drain LBO and Open-Drain LBO options
  • 90ms Minimum LBO Timeout Period
  • Immune to Short Battery Voltage Transients
  • -40°C to + 85°C Operating Temperature Range

Application

  • Monitoring lithiumion (Li+) cells or multicell alkaline/ NiCd/ NiMH power supplies.
