MITSUBISHI <ANALOG ASSP> LOW SATURATION OUTPUT TYPE CURRENT DRIVER
DESCRIPTION
M5265P is quad Darlington current driver (semiconductor PIN CONFIGURATION (TOP VIEW) integrated circuit) which consists of PNP and NPN transistors with clamp diode and it can be driven directly by very small input current. Low saturation output can be obtained by separating the oun [ hg come output stage transistor’s collector from the drive stage tran- or fiw | sistors DRIVE! aT fis] Ours int BE yo {14] 1s CHARACTERISTICS || ci 4 ono THI Vee © Contains a clamp diode. oure oa DRIVEZ © Operates by the “L” level input. com ef [3] ours © Wide operating temperature range .. Ta = ~40°C ~ +86°C * PW= 10 ms, duty cycle < 10% Outline 16P4 APPLICATION Motor drives for various relays or portable printers, digit drives for display elements such as LEDs and lamps, or power amplifiers FUNCTION Unlike the existing common-collector-type transistor arrays, MS5265P realizes 0.25V of low saturation output voltage (typ, I¢ = 0.3A) by separating the drive stage collector from the output stage collector. Therefore, the power dissipation which is determined by the product of the load current and the saturation output voltage can be greatly decreased. The maximum output current is 2,0A and up to 80V can be applied as the output voltage. CIRCUIT DIAGRAM LOW ACTIVE Vee rive 1 ok CLM (CLAMP)
