Description

The ST2042BDR is designed as current limited power distribution switches for application where heavy capacitive loads and short circuits are likely to be encountered. This device incorporate 80mW N-channel MOSFET high-side power switches for power-distribution systems that require multiple powers switches in a single package. Each switch is controlled by an independent logic enable input.

ST2042BDR has ten features. (1) 80mW high-side MOSFET switch. (2) 500mA continuous current per channel. (3) Independent thermal and short circuit protection with overcurrent logic output. (4) Operating range from 2.7V to 5.5V. (5) CMOS- and TTL-compatible enable inputs. (6) 2.5ms typical rise time. (7) Undervoltage lockout. (8) 10mA maximum standby supply current. (9) Ambient temperature range, 0°C to 85°C. (10) RSD protection. That are all the main features.

Some absolute maximum ratings of ST2042BDR have been concluded into several points as follow. (1) Its input voltage range would be from -0.3V to 6V. (2) Its output voltage range would be from -0.3V to Vi+0.3V. (3) Its input voltage range would be from -0.3V to 6V. (4) Its continuous output current would be internally limited. (5) Its electrostatic discharge would be 2kV. (6) Its operating junction temperature would be from -40°C to 125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics about ST2042BDR. (1) Its current low level output would be typ 0.025uA and max 1uA. (2) Its current low high output would be typ 70uA and max 90uA. (3) Its output leakage current would be max 10uA. (4) Its low level input voltage would be min 2V and max 2.5V. (5) Its hysteresis would be yp 100mV. (6) Its sink current would be min 10mA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
