UC1856-SP
- Pin-for-Pin Compatible With the UC1846
- 65-ns Typical Delay From Shutdown to Outputs,
and 50-ns Typical Delay From SYNC to Outputs - Improved Current-Sense Amplifier With
Reduced Noise Sensitivity - Differential Current Sense with 3-V Common-Mode Range
- Trimmed-Oscillator Discharge Current for Accurate
Deadband Control - Accurate 1-V Shutdown Threshold
- High-Current Dual Totem-Pole Outputs (1.5-A peak)
- TTL Compatible Oscillator SYNC Pin Thresholds
- 4-kV ESD Protection
The UC1856 is a high-performance version of the popular UC1846 series of current-mode controllers, and is intended for both design upgrades and new applications where speed and accuracy are important. All input-to-output delays have been minimized, and the current sense output is slew-rate limited to reduce noise sensitivity. Fast 1.5-A peak output stages have been added to allow rapid switching of power FETs.
A low-impedance TTL-compatible sync output has been implemented with a TRI-STATE function when used as a sync input.
Internal-chip grounding has been improved to minimize internal noise caused when driving large capacitive loads. This improvement, in conjunction with the improved differential current-sense amplifier, results in enhanced noise immunity.
Other features include a trimmed oscillator current (8%) for accurate frequency and dead-time control; a 1-V 5% shutdown threshold; and 4-kV minimum electrostatic discharge (ESD) protection on all pins.
