LAPIS ML5236
The ML5236 is an analog front-end IC intended for 14-cell Li-ion rechargeable battery protection systems. With integrated individual cell voltage monitor and charge/discharge current monitor functions, it protects cell overvoltage, cell undervoltage, and pack over-current working with an external microcontroller (MCU).| Part No. | ML5236 |

GENERAL DESCRIPTION
Also, it is equipped with the short-circuit protection function, which autonomously turns off the external charge/discharge Nch-FETs on the high-side power rail without the external MCU.●
FEATURES
● 5- to 14-cell high-precision cell voltage measurement function Built-in 12-bit successive approximation type ADC Cell voltage measurement precision: ±10mV (typ) at cell voltage 4V Cell voltage measurement time: 2ms per cell (typ)● Charge/discharge current measurement function The potential differential between the ISP and ISM pins amplified by 12- or 60-fold, then digitized with the 12-bit ADC. (A single ADC module is shared in cell voltage measurement and pack current measurement.)
● Short-circuit protection function Variable detection threshold between ISP and ISM pins: 50mV/100mV/150mV/200mV (typ) Detection delay time adjustable using an external capacitor
● Built-in cell balancing switch on each cell: Switch ON resistance 6 (typ)
● External charge/discharge FET co...
