| PT7M7433/34/35 ||||||||||||||||| Supervisory Circuit • User-Adjustable Low/High Thresholds with 615mV The PT7M7433/34/35 are single-level battery monitors Internal Reference • Low Current 1.5uA typ SOT23-3 • Single Low-Battery Outputs with internal hysteresis. These devices are offered with PT7M7427xx single low-battery output indicators which can be used PT7M7428xx to indicate three bPaTtt7eMry74c29oxnxditions good operate • Push-Pull LBO, Open-Drain LBO and 1OpLeBnO-Drain system in normal m1odLeB O, weak operate system in low- LBO options power mode , or empty disable the system . • 90ms Minimum LBO Timeout Period GND 3The PT7M7433/34/35 are GuNsDer-3adjustable threshold • Immune to Short Battery Voltage Transient2s BATT • -40°C to + 85°C Operating Temperature Range voltages permitting the user to select the hysteresis range and conseque2ntlByATtThe sensitivity of the system to noise. A wide hysteresis range also prevents chattering Application SOT23-5 PT7M7430xx that can result due to battery recovery after load PT7M7431xx removal.
