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 (VIN) 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 mA, 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 TO220 package and is a competitive replacement for the LM1921, LM1951,LM1952, MC3399, and L9350.
