NJW4822
1-Channel Low Side Switch
GENERAL DESCRIPTION
PACKAGE OUTLINE
The NJW4822 is the single low-side switch that can supply 0.2A.
The active clamp, overcurrent, error flag output and thermal
shutdown are built in with Nch MOS FET.
It can be controlled by a logic signal (3V/5V) directly. Especially, the
NJW4822 is suitable for various Sensors output block as NPN
type. The FLT logic has two versions: Active-high (A-ver) and
Active-low (B-ver).
Also, The NJW4822 is a complementary product to the NJW4832.
