CS8240
500 mA High Side
(PNP) Driver with
On-Chip Flyback Diode
The CS8240 is a fast, PNP high side driver capable of delivering up
to 500 mA 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 (< 1.0 µA, typ).
For device protection, the CS8240 incorporates thermal shutdown,
short circuit current limiting, overvoltage shutdown, and reverse
battery protection. The CS8240 can withstand supply voltage
transients of 60 V (min) and –50 V.
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.
