Description

Block Diagram

Absolute Maximum Ratings

The CS8240 is a fast, PNP high side

driver capable of delivering up to

500mA into a resistive or inductive

load in harsh automotive or industrial

environments. An internal flyback

diode clamp is incorporated for induc-

CMOS compatible and has hysteresis to

minimize the effects of noise. When the

input is high, the output is on. When

the input is low, the output is off and

the supply voltage quiescent current is

very low (<1.0µA, typ). For device pro-

tection, the CS8240 incorporates ther-

mal shutdown, short circuit current

limiting, over voltage shutdown, and

reverse battery protection. The CS8240

can withstand supply voltage tran-

sients of 60V (min) and -50V.

The CS8240 is available in an overmold-

ed 5 lead TO-220 package and is a com-

petitive replacement for the LM-1921,

LM-1951, LM-1952, MC-3399, and L-9350.
