R5426N102AA-TR - Brand New RICOH IC Chips
-
Description
The R5426N102AA-TR is an electronic component model in the product category of IC Chips. It is a protection IC for over-charge/discharge of rechargeable one-cell Lithium-ion (Li+) batteries. This IC includes voltage detectors, a reference unit, a delay circuit, a short circuit protector, and a logic circuit. It is designed to prevent over-charging, excess load current, and short circuits.
Specifications and features
- Low supply current: Typ. 3.0µA for standby current in detecting over-discharge (R5421NxxxC) and Typ. 1.0µA for standby current in detecting over-discharge (R5421NxxxF)
- High accuracy detector threshold: ±25mV (Topt=25°C) and ±30 mV (Topt=0 to 50°C) for over-charge detector, ±2.5% for over-discharge detector
- Variety of detector threshold: Over-charge detector threshold ranging from 4.0V to 4.4V with a step of 0.005V, over-discharge detector threshold ranging from 2.0V to 3.0V with a step of 0.005V
- Built-in protection circuit: Excess current protection ranging from 0.05V to 0.4V with a step of 0.005V, accuracy ±15%
- Output delay of over-charge: 75ms for R5421N111C with C3=0.01µF and VDD=4.3V
- Output delay of over-discharge: 10ms for R5421N111C/112C with VDD=2.4V and built-in capacitor
- Small package: SOT-23-6 / 6-pin
Application Scenarios
The R5426N102AA-TR is commonly used as a Li+ one-cell protector for battery packs. It is also suitable for high precision protectors used in cell-phones and any other gadgets that use on board Li+ one-cell batteries.
