Supervisors

The TLV803MDBZR is a low-power, single-cell lithium-ion or lithium-polymer battery charger from Texas Instruments (TI). It is designed to provide efficient and reliable charging for small, portable devices that require a compact and cost-effective charging solution.

Description:

The TLV803MDBZR is a highly integrated, step-down switching regulator that includes a high-efficiency power stage, a precision linear regulator, and a microcontroller-based charge management system. The device is available in a small, thermally enhanced 10-pin WSON package, making it ideal for space-constrained applications.

Features:

1. Input voltage range: 4.5V to 5.5V
2. Output voltage range: 4.2V to 4.4V (programmable)
3. Charging current: Up to 500mA (programmable)
4. Charging modes: Constant current (CC), constant voltage (CV), and trickle charge
5. Battery temperature monitoring: Integrated thermistor for over-temperature protection
6. Charge status indicators: Charging, charged, and fault indicators
7. Protection features: Over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), and short-circuit protection (SCP)
8. Low quiescent current: Less than 2µA in standby mode
9. Programmable charging timer: Adjustable charge termination timer
10. Small form factor: 10-pin, 2.5mm x 3mm WSON package

Applications:

1. Portable electronic devices: Smartphones, tablets, and wearables
2. IoT devices: Smart home devices, fitness trackers, and smart sensors
3. Medical devices: Personal health monitors and portable medical instruments
4. Consumer electronics: Bluetooth headsets, wireless keyboards, and gaming controllers
5. Industrial equipment: Portable data loggers and handheld test equipment

The TLV803MDBZR offers a compact, efficient, and reliable charging solution for single-cell lithium-ion or lithium-polymer batteries in a wide range of applications. Its low-power consumption, integrated protection features, and small form factor make it an ideal choice for designers looking to minimize the size and cost of their battery charging systems.
