It is comprised of two source/sink driver pairs rated for continuous operation to }3 A. It can be connected to drive two independent loads or a single load in the fullbridge configuration. Both drivers include output clamp/flyback diodes, input gain and level shifting, a voltage regulator for single supply operation, and pulse-width modulated output-current control circuitry. Inputs are compatible with most TTL, DTL, LSTTL, and low-voltage CMOS or PMOS logic. The peak output current and hysteresis for each source/sink pair set independently. Output current, threshold voltage, and hysteresis set by the user’s selection of external resistors. At the specified outputcurrent trip level, the source driver turns off. The internal clamp then allows current to flow without additional input from the power supply. When the lower current trip point is reached, the source driver turns back on. The UDN2962W is in a 12-pin single in-line power-tab package. The tab is at ground potential and needs no insulation. For highcurrent or high-frequency applications, external heat sinking may required. * TTL/PMOS/CMOS Compatible Inputs (this posting is the responsibility of the poster) |
