Description for the TPIC6B273
The TPIC6B273 is a monolithic, high-voltage, medium-current, power logic octal D-type latch with DMOS-transistor outputs designed for use in systems that require relatively high load power. The device contains a built-in voltage clamp on the outputs for inductive transient protection. Power driver applications include relays, solenoids, and other medium-current or high-voltage loads.
The TPIC6B273 contains eight positive-edge-
triggered D-type flip-flops with a direct clear input. Each flip-flop features an open-drain power DMOS-transistor output.
When clear (CLR\) is high, information at the D inputs meeting the setup time requirements is transferred to the DRAIN outputs on the positive-
going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock input (CLK) is at either the high or low level, the D input signal has no effect at the output. An asynchronous CLR\ is provided to turn all eight DMOS-transistor outputs off. When data is low for a given output, the DMOS-transistor output is off. When data is high, the DMOS-transistor output has sink-current capability.
Outputs are low-side, open-drain DMOS
transistors with output ratings of 50 V and 150-mA continuous sink-current capability. Each output provides a 500-mA typical current limit at
TC = 25°C. The current limit decreases as the junction temperature increases for additional device protection.
The TPIC6B273 is characterized for operation over the operating case temperature range of -40°C to 125°C.
