Data Sheet
PT7M7433/34/35
µP
Supervisory Circuit
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 low-power
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.
