SLG59M1638V数据手册集成电路（IC）的配电开关负载驱动器规格书PDF

描述 Description

A 1.6 mm², Dual-channel 45 mΩ/2 A Load Switch with Reverse-Current Blocking, VOUT discharge, and Active HIGH ON-OFF Control

The SLG59M1638V is a dual-channel, 45 mΩ PMOS load switch designed to switch 1.5 to 5.5 V power rails up to 2A in each channel. When either channel is enabled, reverse-current protection will quickly open the switch in the event of a reverse-voltage condition is detected (a VOUT > VIN + 50 mV condition opens the switch). In the event that the channel’s VIN voltage is too low, the power switch also contains an internal UVLO threshold monitor to keep or to turn the switch OFF. For fast load turnoff when either switch is disabled (ONx = HIGH-to-LOW), each channel has its own fast discharge transistor that connects an internal 150 Ω RDSON transistor to ground. Each power switch is independently controlled via its own low-voltage compatible CMOS input. Designed to operate over a -40°C to 85°C range, the SLG59M1638V is available in a RoHS-compliant, ultra-small 1.6 x 1.0 mm STDFN package.
