PT7M7433
PT7M7433 is uP Supervisory Circuit manufactured by Pericom Semiconductor.
Features
Description
- User-Adjustable Low/High Thresholds with 615m V
The PT7M7433/34/35 are single-level battery monitors
Internal Reference
- Low Current (1.5μA 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 b Pa Ttt7e Mry74c29oxnxditions: good (operate
- Push-Pull LBO, Open-Drain LBO and 1Op Le Bn O-Drain system in normal m1od Le B)O, weak (operate system in low-
LBO options power mode), or empty (disable the system).
- 90ms Minimum LBO Timeout Period
