PST9346 General Description

The PST9346 is a kind of reset type IC. It functions in a variety of CPU systems and other logic systems to detect power supply voltage and the system accurately when power is turned on or interrupted. It is ideal for use in battery check circuits for products using batteries, as they have ultra-low current consumption and a high precision voltage detection function. The typical applications include: (1)reset circuits in microcomputers, CPUs and MPUs; (2)logic circuit reset circuits; (3)battery voltage check circuits; (4)back-up power supply switching circuits; (5)level detection circuits.

There are some features as follows: (1)high precision voltage detection: VS±2% max; (2)ultra-low current consumption: ICCH=2.0 A typ, ICCL=2.0 A typ; (3)low operating limit voltage: 0.65 V typ; (4)hysteresis voltage provided in detection voltage: 50 mV typ; (5)output current high for ON: 5 mA min; (6)detection voltage can be selected as desired within a range of 1.9 V to 4.6 V.

The following is about the absolute maximum ratings: (1)storage temperature, TSTG: -40 to +125; (2)operating temperature, TOPR: -20 to +75; (3)power supply voltage, VCC max: -0.3 to 10 V; (4)allowable loss, Pd: 150 mW. Then is about the recommended operating conditions: (1)operating temperature, TOPR: -20 to +75; (2)power supply voltage, VCC: +0.85 to +10 V.
