NID5100
1.2 V to 5.5 V, 1.5 A input polarity protected, low quiescent current ideal diode
The NID5100 is an integrated ideal diode capable of replacing traditional diodes in low voltage systems unable to tolerate the high voltage drops of conventional Schottky components.
When enabled and forward biased, the device regulates the voltage between the IN and OUT pins resulting in a forward voltage drop, VREG, approximately an order of magnitude smaller than similarly rated Schottky diodes. When OUT voltage is higher than IN voltage, the NID5100 becomes reverse biased with very low leakage current.
Integrated Reverse-Polarity Protection (RPP) prevents damage to components connected to the OUT pin in the event of a supply voltage reversal.
The enable pin, EN determines if NID5100 operates in forward regulation mode or body-diode mode.
A variety of power OR-ing configurations are supported for system flexibility:
Two, or more, NID5100 devices in combination
NID5100s and conventional Schottky diodes
An NID5100 and an external PMOS
An open-drain status pin, ST, is high-impedance when NID5100 is enabled and in forward conduction and low when disabled or in a reverse biased condition. The ST pin can be used to control an external PMOS to OR an additional supply, or connected to a microcontroller to indicate the status condition of NID5100.
The NID5100 is available in a standard TSSOP6 (SOT363-2) with 2.1 mm x 1.25 mm x 0.95 mm body package compatible with industry SC88/SC70-6 packages providing a small PCB footprint compared to conventional low-current diodes.
