CS8240
500mA High Side (PNP) Driver
with On-Chip _{Flyback Diode}
Description
Features
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-
tive 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 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.
