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.
