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