Respectively offered in 3 x 3 mm, 14-pin TDFN and 12-pin TQFN packages, MAX8844 and MAX8845 are 28 V, dual-/single-input, linear Li+ battery chargers with battery detection and overvoltage-protected outputs. Ability to provide resistor-adjustable fast-charge and top-off current thresholds promotes flexibility, which is further extended by auto-booting assistant circuit. While MAX8844 has 2 overvoltage-protected LDO outputs, MAX8845 has one overvoltage-protected LDO output.
Highly Flexible, 28V, Dual-/Single-Input Battery Chargers with Battery Detection and Overvoltage-Protected Outputs
Dual-/single-input, linear Li+ battery chargers for cell phones and smartphones.
SUNNYVALE, CA-August 20, 2009-Maxim Integrated Products (NASDAQ:MXIM) introduces the MAX8844/MAX8845 28V, dual-/single-input, linear Li+ battery chargers with battery detection and overvoltage-protected outputs. These devices enhance flexibility by providing resistor-adjustable fast-charge and top-off current thresholds. To further increase flexibility, an autobooting assistant circuit distinguishes input sources and battery connection, and also provides an enable signal for system booting. The MAX8844/MAX8845 are ideal for space-constrained applications such as cell phones and smartphones.
The MAX8844 has two overvoltage-protected LDO outputs for supplying low-voltage-rated USB or charger inputs, while the MAX8845 has a single overvoltage-protected LDO output. This integration eliminates the need for external overvoltage-protection ICs. Both devices integrate a battery-pack detection circuit that disables the charger when the battery pack is absent.
The MAX8844 is packaged in a 3mm x 3mm, 14-pin TDFN, while the MAX8845 is available in a 3mm x 3mm, 12-pin TQFN package. Prices start at $1.42 (1000-up, FOB USA). User-friendly evaluation kits are available to speed designs.
