Product Summary
The UAA4002DP is a control circuit for fast switching transistor.
Parametrics
UAA4002DP absolute maximum ratings: (1)VCC, supply votlage: 15V; (2)V+, positive supply voltage (power state): 15V; (3)V-, negative supply voltage (power stage): -10V; (4)V+-V-, voltage between pins 15 and 2: 16V; (5)IB1, positive output current: 1.5A; (6)IB2, negative output current: -3.5A; (7)IC, current into input Ic (internal protection diodes): ±5mA; (8)minimum value of resistors Rt and Ro: 5kΩ; (9)voltage between input and V-: 18V; (10)Tj, junction temperature range: -40 to 150℃; (11)Tstg, storage temperature range: -40 to 150℃.
Features
UAA4002DP features: (1)direct drive of the switching transistor; (2)self regulated positive base current (1A max); (3)negative base current ensuring fast turn-off (3A max); (4)the output current can be increased by means of one (or more) external transistor; (5)minimum conducting time to allow the discharge of a rdc network; (6)protection against saturation fallure of the power transistor during conducting period, with adjustable detection treshold; (7)instataeous-collector current limitation; (8)positive supply (Vcc) monitoring; (9)negative supply monitoring with adjustable threshold; (10)on-chip thermal protection; (11)programmable maximum on time; (12)TTL and CMOS compatible input; (13)can be driven with alternate pulses; (14)adjustable delay between the rising edge of the input signal and the beginning of the positive base drive.
