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 inductive loads. The input (V
IN
) is TTL and
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 protection, the CS8240 incorporates thermal shutdown, short circuit current
limiting, over voltage shutdown, and
reverse battery protection. The CS8240
can withstand supply voltage transients of 60V (min) and -50V.
The CS8240 is available in an overmolded 5 lead TO-220 package and is a competitive replacement for the LM-1921,
LM-1951, LM-1952, MC-3399, and L-9350.
