Ultra small package of S-19682/19683 Series

 The industry's smallest* ultra-small package

Small:  The 1-channel high side switch with 36V input, 600mA output, a current monitor function, is housed in the industry’s smallest* package, HSNT-8(2030).
Space:  Unlike conventional multi-channel products, S-19682/3 Series allows a higher degree of board design freedom to simplify board layout design.
Flexible:  S-19682/3 Series can flexibly accommodate any number of cameras such as driver status monitors or drive recorders.

With the increasing multi-functionality of automotive cameras, antennas and sensors, S-19682/3 Series with its capability to offer connection diagnosis of a variety of applications is a “Small, Space, Flexible” solution that makes it all work.


Limit current accuracy of S-19682/19683 Series

 Simplifies connection diagnosis

S-19682/3 Series is equipped with a CSO pin to output a voltage proportional to the load current.
Since the CSO pin doubles as a status output pin, an MCU can easily monitor the current of cameras, sensors, antennas and other devices as well as diagnose their connection status (open, normal, short to ground and short to power supply) simply by monitoring the CSO pin voltage.
S-19682/3 Series contributes to the safety of the automotive devices with a simple circuit configuration.

 High-accuracy current limit

S-19683 Series limits current with a high accuracy of ±10% to ensure that load current does not exceed the set value.
Since the limit current value can be set in the IC, peripheral components do not cause dispersion. Moreover, as the limit current value can be selected in 10mA steps, limits can be closely tailored to the connected load.
As a result, there is no need to set an excessive margin for the DC-DC/LDO stage prior to the high side switch, which reduces the size of the entire ECU and its cost.
